Question:
We have a 2015 Thor Outlaw 29H, Ford E450 class c toy hauler motorhome. My husband is a quadriplegic and we made the garage part into bedroom. He rides back there most all the time. It is a lot rougher riding in back than it is in front. He had different shocks put on but didn’t help much. Is there something that would work on back to make it a smooth ride for him. Thank you, Brenda Smith

Hey, Brenda! More than happy to help!
The best place to start is to get the rear sway bar part # RM-1139-147. This is going to help keep prevent side to side movement when taking on some sharper turns and cross winds.
After that, if more support is needed, I recommend getting a set of Sumos from SuperSprings. They have a 3k lbs kit ( # SSR-106-40-1) and a 7k lbs kit (# SSR-106-54-1). I wanted to give you both weight options since the garage is your living space and not housing something like a side-by-side or UTV. I do want to share that SuperSpring does have a 30-day satisfaction guarantee. So if you absolutely hate it, you can return it and get a different weight capacity or something completely different. Normally we don't take anything back that's been installed so wanted to make sure that you knew you wont be stuck with something that you hate.
Lastly I want to say that you and your husband transforming the back of the toy hauler to fit your exact needs is absolutely ingenious! Let me know if you have any questions about these kits or any other parts we carry. I'm here to help!
