Bouncy Towing 290RLT

Went on the maiden voyage last week and was very pleased with everything however I did notice extended bouncing on bumpy roads and roads with hills and dips. I assume this is due to the light pin weight and the double slides cantilevered on the back. Is anyone else experiencing this? From what I have read an air pin box could help but I don't know anything about them and don't want to make a very expensive mistake. I am towing with a 2005 Chevy 2500HD D/A and a Pullrite Superglide. All opinions are welcome.

I've experienced similair since I've switched tow vehicles. I'm trying to load the camper different and intentionally increase the pin weight. I'll scale it on our trip next week annd see what the pin weight is now.

If you haven't already, you should get your combo over a set of scales and see what your current pin weight is. Your spec by dry numbers is 16.1% pin the floorplan I'd expect that the pin weight would grow quite a bit when loaded as you don't have many storage areas behind the camper's axles. Our floorplan is a rear kitchen and it's a lot harder to increase the pin weight.

I have to agree with Dave in that an increase in pin weight does seem to help.We have the bigger an albeit somewhat longer 320 unit and that may also play into how a particular trailer reacts.I've also noted it here in these forums that some folks fill up there fresh water tank and depending where the tanks are situated,this too can have a stabilizing effect in the bouncing you feel. This is our first fifth wheel and I have to say compared to our last 30ftTT,it seems to pull quite nice.On our 2000 mile round trip last fall I found it pulled rather smoothly. Just my .02

Bouncy Ride....

As we have ~1350 pin weight empty in the 290RLT, it does help to make sure that is taken into account loading, so as not put too much weight aft of the wheels. As you know, the fridge, sofa and a lot of 'heavy' storage is at or aft of the trailer wheels...
Our 290 came with the "TrailAire" roto-flex rubberized pin box, and yes it does flex enough to smooth out the ride over Railway Xings, overpasses, and roller-coaster concrete like that found west of Oklahoma City on I-40.
I dropped my speed down a tad over those kinds of 'speed bumps' and that helped also.
I also run with Firestone air bags and they keep things fairly firm over the rear axle.

I have to agree with the others, on first try loading the unit different to see if that will play a difference in the ride.

I have a 5th Airborne pin box, there are others that for the most part do the same thing. That is take most of the "chucking" out of the ride. They are a hinged type of king pin with airbag and or shock. Those work together to make the ride more enjoyable. I feel that even though the loading plays a part it will boil down to getting a different pin box.
