Hey Bill, the part # T35AV is what you need as the part # TMBRSP35B that you referenced does not work on motorhome chassis like you have. Price difference would be for the different brackets etc. Are you wanting to improve handling?

Yes, I would like to improve handling. Main issue is sway side to side due to the top heavy vehicle. I have put sumo bumpers on the front and super springs on the back. Still a lot of sway side to side over uneven bumps and such.

Since the pin weight of your camper is 2.1k, I recommend going with the LoadLifter 5000 opposed to the 7500. While technically there is not reason you couldn't use the 7500 kit, it really is not necessary for a camper like yours. Generally the…
