You might want to reweigh your truck Friday with full tank and without trailer. I assume you will have more in it then you? Other people, gear, tools, food, etc.? This will give you a more accurate tongue weight number which will be shown in the Results section of the calculator I referenced above.

I weighed the truck and trailer (some supplies but no water in the tanks) with WDH, w/o WDH, and then solo. I think I am good. See attached. The only weight I am busting is my Rear GAWR by 70 lbs. I had a chair and few things in the bed so I think I can get her back below the Rear GAWR. But, I am installing a set of Roadmasters. I did feel a little porpoising though. Any thoughts?

Can someone who is more knowledgeable than me comment on my numbers? Thanks.

Sorry--I clicked the "Like" button but didn't comment. The front axle (with WDH) is 3240. Truck by itself is 3220. The WDH hitch may be a bit tighter than necessary.

Truck GVWR is 6500. Truck is 6160 as currently configured. What are the axle GAWRs?

Trailer GVWR is 6995 and total weight is 5680. That's remarkable. Trailer was loaded for camping? (Food, clothes, etc?)

When everything is hooked up, is the camper parallel ("level") to the road?

Also, what is your GCWR?

Our 22mle weight was 5580, that’s ready for camping. We don’t carry water in fresh and generally pack light. Just two of us.

Truck GAWR's - Steer was 3220 and Drive was 2460
Trailer was loaded modestly but no water. Food, clothes, chairs, and few other items plus set up equipment (blocks, cords, hoses, etc.)
It road level.
GCWR was 11,300.

The rear axle's rating can't be 2460. The rating. From the sticker. Not how much it weighed. Please see https://gdrvowners.com/towing-and-hi...ehicle-ratings if my question doesn't make sense (yet).

These numbers are from another person who has a F-150 2.7l EB and the 22mle. How does your truck’s rating numbers compare to his?

TV is 2019 F150 Lariat, 2.7EB, 3.55, tow package, 145" wheelbase (short bed).
Front GAWR 3450
Rear GAWR 3350
GCWR 12,900
Payload sticker 1426
GVWR 6600
Max tow 7600
Max tongue 1320 (with WDH)

Oh, from the stickers:
Front GAWR 3450
Rear GAWR 3350
GVWR 6500
Payload - 1379

In post 17 it states concern about being over the rear axle's GAWR. The weight ticket shows 2920 with the WDH connected--below the 3350 rating. The front axle is also below (3240 measured, 3450 rating) and the GVWR is below (6160 measured, 6500 rating).

The numbers (to me) look good. Are you seeing something I'm missing?

Thanks Howson. My mistake on the number. It was busting w/o the WDH hooked up. The numbers are good but what I am experiencing is porpoising. Maybe I have too much weight on the front axle. Adjust the WDH to transfer a little more weight on the rear axle?

The only time I experienced porpoising is when I had the air bags in my truck with a high psi (I was experimenting).

A fellow forum member pointed out that ny F-350's manual has a specific procedure to properly hook up a WDH hitch (fender height measurements are taken). Does your F-150 have something similar in the manual? I do think there's too much weight pushed forward onto the front axle.

Again...I have limited experience with the issue. Hopefully others will chime in.

Porposing ( how do you spell that word?) will be generally felt while towing any type of bumper pull trailer. Some times the condition is worst than others but dips or road conditions can cause this in the best set up rigs. Usually I have had this happen when having too much tongue weight. When everything is loaded and hooked up you should have a pretty level sitting unit. Measurements , as Howard has eluded to , will help with this setting. Measuring the truck fenders , front , with the truck loaded and ready to go. Then when you attach the RV and WDH take measurements again. Adjust the WDH until you get close to the original measurement on the front as you can. This should get you pretty close to where you need to be. But again trial and error sometimes is the best thing. When loading the trailer it is easy to add weight here and there that will make the towing different each time. When we had our previous TT I got pretty good at seeing what we were packing and I new whether I needed to change my WDH setup or not, I would usually tighten it up a link or loosen it by a link and had pretty good luck with that.

Of course that usually means too little weight on the back axle which can cause the proposing. Too little weight on the back axle also causes reduce traction for your back/drive axle which can cause problems in the rain/hydroplaning.
