" A little tongue weight", when you say that do you know what the tongue weight is? If you have too little tongue weight this will cause issues when towing. There are certain bumps and road conditions that just can not be removed from the towing equation, they cause issues no matter what one does.

Might also be weight distribution in the trailer. What is the tongue weight?

I had a filling this would come down to knowing the Tongue weight. I am planning to go back through the setup and figure out the Tongue weight again. I want to say I had it at 400 lbs, but I couldn't find that paperwork.

That could be your whole problem, if the gross weight is achieved #7850, 15% of that is around #1000. Tongue weight is very important especially with a travel trailer.

Keep in mind the black tank on the 2600RB is at the rear of the camper (right underneath the toilet). The gray for the shower is just forward of the black tank. Both are behind the axles. Any contents in those tanks will dramatically alter the tongue weight.

If you don't already have one, this scale can be very useful. I bit the bullet and got one so I'm sure how everything is loaded.

Thanks Howson, I never travel with the tanks full (always Empty). I know that's a game changer for sure.

I live in the Fort Worth Texas area, any Chance there is a service around me that Can do a complete setup to verify my distribution is correct? I've never needed to reached out for help until I got this longer camper.

The first thing I would do is replace the Rancho shocks with a good set of Bilsteins. https://www.shocksurplus.com/collect...SAAEgL9PfD_BwE

I have had Rancho's on previous trucks and they are junk (in my opinion) especially as yours are 4 years old. Also in your pihoto it appears the trailer is slightly nose down which can exaggerate the buck by pushing the rear of the truck down and forward, Can you possibly raise your ball up to correct? Just an idea to try

Hope this helps

I totally agree with you on the Rancho's (I am not a fan) I was talked into these the last time I replaced my shocks and wished I didn't do it. I have the bilstein shock on my front steering stabilizer and love it.
My plan is to do another leveling evaluation now that I have done 4 trips with this setup. The tricky part is getting the Tongue weight where I need it. It would Be nice to have what trkester suggested (buying a scale). Once I recheck all the settings I will look at shock replacement.

The more I dig into this evaluation again, I’m finding it harder to wrap my head around the distribution adjustments.
So, the adjustments on the head (bolt and pin with washer) crate the tilt of the head to push tension on the distribution arms, but doesn’t the L-Brackets do that as well? Or Are the head adjustments for fine tuning?
Man getting older sucks!

Within 10 miles of downtown Fort Worth there are four CAT scale locations. Want to find one specifically close to you? Go to https://catscale.com/cat-scale-locator or download the Cat Scale Locator app https://catscale.com/cat-scale-apps/



While you're downloading the scale app, get the Weigh My Truck app. Super easy to use and very convenient. You'll want to take at least THREE measurements.

1) Just the truck
2) Truck and camper -- weight distribution NOT engaged.
3) Truck and camper - weight distribution engaged

Post the three results (you'll get an email from CAT with the weight tickets if you use the app) and we can definitely help from that point.

Guest -- you've got a 2600RB, right? Any input for this new owner and his setup?

Tilting the head back creates more pressure on the bars, which brings to mind a question, What is the weight rating for the bars on your hitch set up? This is critical in the weight distribution, I would guess you will need at least #1000 bars, #1200 would be better.

Jim,

Do you have any help to pass on to this owner? same model RV 2600RB.

Howard,

I have a 2600RB on a half ton and I had some porpoising issues on some of the Michigan roads a few years ago. Ok who does not have issues on Michigan roads? My truck does have Bilstein's but I only added them because I added unsprung mass in the E rated Michelins from C rated GY tires. Otherwise I would have used the same monotube Ranchos so this is a tough call. Its important to use a monotube shock since they will exhibit better control with their larger piston diameter. To correct most of the issue I added more bar and use 6 washers if this helps. I cannot see the angle on the OPs hitch but to load the bars on the equalizer, more washers are needed. Not in raising the brackets since they should be parallel to the trailer frame.
I also added airbags to the truck to control some of this as well since the half ton needed some help to prevent bottoming on those same no bottom roads. I do not have a light tongue weight being at around 960lbs loaded with full water.
I did not catch which equalizer hitch the OP uses where I have the 10k version and if I had to buy the hitch again, I would have purchased the 12K version but I have messed around and now have good control with the 10K model.

I hope this helps where each individual system requires its own settings. I would start first with new monotube shocks and go from there.

Jim
