The cabin jumps out of frame

My 171 is a 2013 model. I bought it 7 months ago. I don't know how to describe this issue but here goes. As I drove it on a trip the two up front sides jumped out of the exterior one inch framing. So I removed that one inch right angle framing and replaced it front to back on both sides with two inch steel right angle framing. I thought I solved the problem but it did not. It seems the cabin jumps up while I am driving (or going over bumps) and  moves out of the side 2 inch framing. Consequently the door is no longer aligned and I have to push the front of the cabin back into position.  Can someone please help me find the solution to this problem.  Thanks.  Lonetraveler  

Yes, I can post a picture and will do so as soon as I get home. Thanks

Hi Lonetraveler,  sorry to hear you are having this issue. This is a serious issue with no easy fix. The fact that the sides/body of the camper are moving around on the floor, points to wall separation at the joints, probably due to water intrusion causing the wall to degrade and the fasteners to break free. Basically the walls have to be rejoined to the front and the floor. Having an RV repair shop do that is probably best, but it is going to be costly, probably challenging the value of your rig. 

Thank you. I guess I will take a look at the floor and see if this old man can resolve the problem. It was so nice you gave me the bad news, but at least now I know what needs to happen.
