  • Hitch Rack from Harbor Freight Wheelchair Carrier (Mod)

    Long post warning!

    This mod has been a work in progress for many months. It's been road tested (except for the cover) and performed beyond my expectations. There is so much to this mod that I don't want to write it all out if there's little interest, so I guess what I'll do is hit the highlights and will respond with more information as desired.

    First--why?

    The DW and I have enjoy boondocking and moochdocking. To do this we needed a way to ensure we can dump during an extended stay where there are no facilities. This meant a sewer tote. I wanted the largest one I could reasonably carry. As I soon found out, "reasonable" and "carry" are subject to interpretation. Camco may think a 36 gallon, four-wheel sewer tote is easily portable but in reality hanging it from the ladder wasn't going to happen. So a solution was required. What you see below is the result of an evolutionary process to come up with an answer.

    One of the additional features I added as the project unfolded was to add a way to carry the tote's many accessories. Then I thought, why not all the outside stuff? Outside stuff means anything that can get wet without being damaged and was not stored in the camper already. All of this was in the truck bed.

    The totes you'll see in pics below are Stanley STST33031W 13 Gal Mobile Chests that I bought at Walmart a year or so ago. (These fit perfectly in my truck bed under the tonneau cover even with my LoadAll ramp in the bed.) The issue was dragging the storage chests out, then putting them back in, then out again...etc. As anyone who's followed my threads knows that I despise repetitive logistics and I'm always looking to make things better/faster/easier. To my delight I found the storage chests fit on top of the modified storage rack almost perfectly. (It's good to be lucky sometimes.)

    So enough words. Below is the finished product with the cover and without the cover.

    What may not be obvious in the picture above is that I do not need to remove the two chests at the rear to access their contents. These two chests contain the frequently-used items: plumbing (fresh water) hoses and adapters are in the left chest and all the sewer adapters and black hoses are in the right chest. Loosen the red strap that holds the chest in place, it slips over the edge of the chest, and then there's easy access to the contents! If I'm ever at a steeply sloped spot...I'll figure it out.

    Let me repeat here that this is not a waterproof setup and not meant to be waterproof.

    What you see above started life as a Harbor Freight carrier. It's been heavily modified as it's probably twice as high as the original and the ramp is nearly cut in half. Below is the original ramp configuration (pic from HF website).

    It's the details of how it got from the HF configuration to how it is now that could take several posts...so I'll hold fire until I know there's interest.

    To satisfy Guest (I know what you're thinking, Jim): How much does this setup weigh? Everything, and I mean everything, added to the OEM trailer hitch weighs 214.2 lbs. This is well below the 300lbs maximum rating of the hitch. I also took pains to ensure there is no movement, none, in any direction once it is secured to the camper. I even modified it to snug it up as close to the camper as possible to remove the lever factor due to how far it originally stuck out from the hitch. I could write a long post on that topic alone. (Like I said, this was a long project.)

    Another obvious question: What are you doing with the bikes? I think I have a solution, but it hasn't been road-tested yet. In about a week there's a trip planned so I'll report from the road on how it's going with the Goldwing and the bicycles in the truck bed at the same time. (Yep, you read that right. Not ready to share this story yet so stay tuned!)

    I'd like to close by bragging on my DW. The cover you see in the pictures was intended for use on a Blackstone grill. She bought it at Lowes. She sewed it to just the right size and then we added grommets to keep it blowing off during transport. My DW is clever and skilled with a sewing machine! Andi -- tagging you to make sure you see this.

      Good question. Wish I'd weighed it with the Sherline when I had everything off yesterday. Not going to pull it all off again.

      I'm headed the opposite direction of the CAT scale I normally frequent, so will have to see where there is one on my route to get weights. I'll have the 'Wing with me, too, so I'll be max'd out.

        Hi Howard,

        I am reminded of a modification to the hitch receiver crossbar bolted the RV frame rails, as made by another Reflection owner. I saved these pictures a log time ago, so I can't give proper credit . . . maybe someone will remember who accomplished this mod? Even though you are within the weight limits and have minimized play/bounce, more than one connection between storage structure and trailer might be worth considering.

          Cate&Rob -- I've got an inspection of the rack and interface with the camper on my "To Do" list at the end of each travel day on my forthcoming trip. When I return home I'll remove the assembly and do a closer inspection to see if I can find any signs of stress. The ultimate would be a Non-Destructive Inspection scan of the main support (like we did on aircraft structures) but that's going overboard. (Pun intended?)

          Your concern is exactly why I held off posting this until I had real-world use of the rack behind me. It's traveled >600 miles without incident. I can watch the rack with my rear-view camera and everything looks very good.

          As always, if something wayward happens I'll report the bad news. Sometimes we learn more from failures than from successes?

            If I were to "improve" the attachment to the trailer frame rails, rather than modify the existing crossbar that bolts to the frame rails and carries the receiver, I would use the original as a model and set it aside for possible re-installation some day. I would go with two receivers (three might be difficult to line up when attaching the carrier) and I would extend the plates that bolt to the frame rails for another bolt or two on each side. A relatively simple fabrication for a welding shop, particularly if they had the original to model the new one from. (There I go . . . spending your money again )

              Cate&Rob howson Rob and Howard, what scares me more about the hitches on the back of the units is more about stresses due to design. If you look at the way that receiver is designed, all of the forces of the weld are amplified by the hang out before considering the actual load and its distance from the welds. I would think that the hitch should be reversed where the cross tube is as close to the rear and the receiver tube is on the bottom or shortened such that it does not have as much "arm" prying on the weld.

              Rob's pictures must be of an older design because the one on my trailer does not have cross bolts, but is welded to the bottom of the frame. Again it looks backwards to me. Also in the mod picture it's hard to tell, but it appears as if they chose to cut the cross tube and insert the additional receivers. This could be a really really bad thing as the properties when cut and parts removed are different. If you notice the factory chose to butt the receiver to the cross tube and reinforce top and bottom.

                The 2 end brackets that are "welded" to the frame is what concerns me , at least on my unit. There is only a couple of 1" long stitch welds on the outside edge of the bracket.

                Jlawles2 I would like to see a picture of your hitch welded to the frame , this has not been a practice of GD or Lippert that I have seen but could be the "new" way.

                  Cate&Rob and Jlawles2 ,

                  Since the loading seems to be of interest (not surprising!) I'll show what I did to generate further constructive feedback.

                  In the top picture of the two below you can see where the hitch pin was supposed to go for the rack. Notice how far back the rack is from the camper.

                  In the lower picture is the location I created.

                  I also tapped ("created threads") for the locking pin.

                  To stop any lateral or vertical movement I ended up combining two different anti-rattle devices. (I only used one part of the device on the left shown by the arrow.) Between the two combinations and the screwed-in locking pin the rack is absolutely rock solid.

                  I know very little about welding, bonds or "proper" hitch attachment techniques. I'll leave that topic to the engineers and experienced metal workers like Country Campers . Below is how my trailer is configured. For now "it is what it is".

                    Don't get me wrong . . . I think you have done an "above & beyond" process of attaching the carrier to the receiver. Perhaps we engineers are "over engineering" this . . . like, we have never done that before .

                    Our discussion seems to be focussing on how the receiver frame is attached to the trailer. In looking at your last picture, there appears to be a difference in what this is bolted to on the left side vs the right side . . . or is this just the perspective of the camera?

                    It would be interesting to video the motion of your carrier on a reasonably rough highway.

                      Cate&Rob -- it's bolted on both sides. No difference.

                      I do have a GoPro...but I have only used it when riding my Yamaha WR250. I'd have to record the rack without the cover, too, since the inevitable flapping will remove all possibility of determining what's really happening. Always another interesting thing to learn how to do.

                          When I added mine, I didn't want to go through welding, etc. All I wanted was stabilization. So got a couple bolt-on's (https://www.amazon.com/Quick-Product.../dp/B013U6NGGK) and some 2" extentions along with u-bolts and some painted Oak spacers to get up under the rack. I get zero movement and didn't have to do anything permanent.

                          Again, these bolt-on's are not weight bearing, only used to stop the wiggle. The original 300lb center receiver is the load bearing connection.

                          I also added an led light strip (https://www.amazon.com/Wigbow-Tailga.../dp/B07HCK5SM5) to the rack to make sure I wasn't blocking the signals.

                          The box is used mainly bulkier things like my patio mat, sewer slinky, etc that take up lots-o-room. Also a simple place for the power cord. Click image for larger version

                            That is very interesting. Lippert must have made a change or Grand Design requested this.
                            With the 2 tubes welded to the frame it would be easy to find tubing to slide thru the id of that tubing.to make a well supported rack. Some of the other manufactures have a folding rack attached to the well supported and beefy bumper , I wish GD would offer this or make this standard.

                              9 Oct 22 Update

                              After 17 months, the custom rack is now removed from my camper. :( It was a spectacular success. I really enjoyed the convenience of having all the "outside" stuff, well, outside. There no signs of stress on the rack or any of the welds, so I'd say it held up perfectly.

                              What's changed that requires the removal of the custom rack is an e-bike purchase for the DW. Her new bike must be well protected, so it will not ride in the truck bed like our old bikes did. The only spot to put her bike is on the rear of the camper (no way her bike is going on a tongue rack up front)...so...a (new) bike rack is going back on the rear of the camper. The rack is a Swagman e-Spec that I'll write up separately once installed.

                              There's no where to use my custom rack, so I'll have to figure out something clever to repurpose it and, of course, figure out where all the "outside" stuff is going. Darn it.
