Travel Trailer Disaster Help

Well I called the manufacturer and got no satisfaction. They are basically stating to me that the camper should not be out in weather below 40 degrees. They also stated that the camper can be repaired and will be repaired. I demanded a new unit since it will not be the same after it is repaired. They said it would be the same since they do not believe water damage even if the insulation was completely soaked and almost an inch of water or more ran through the walls and flooring. I even have a video of tons of water running out. They said since it worked at the dealership then it should not have any problems after that. If it does then it had to be something other than them.

I am going to put the dealership in a box tomorrow and request to trade the camper in. When they give me a low value on the camper then I am going to ask why and watch them squirm with an answer.
