Thank you everyone for you answers. We truly appreciate them.
It is a 2017 Palomino Model 201SS on a Lippert frame. To clarify, when I said hauling water, I meant the fresh water tanks were full because we were going into the mountains for the weekend. Not hauling extra tanks of water inside the trailer. According to the manufacturer, we could haul something like 500# of supplies. The full tank of water was around #250. There was no mention in the owner's manual, or any paperwork for that manner, that says the trailer should not be towed with a full tank. I can guarantee that we did not have that much in there. I know Lippert won't care. I'm just exceedingly frustrated with their response. I will add pictures as soon as I figure out how to. I'm truly bothered by the trailer manufacturer and Lippert's response because this easily could have been a fatal accident if it had happened while travelling at highway speed.
Unfortunately we do not live where I bought the trailer. We have it at the local dealer and they are worthless. They are being punitive since I did not buy the trailer from them. They have told everyone that the frame is just "bent" even though we have pictures and proof that all the welds have failed. Needless to say, we are trying to get the trailer back to the original dealer so that we can get an accurate assessment.
We have had 2 certified welders assess the trailer and although they feel like they could fix it, they have both said that the trailer body needs to come off the frame and the whole frame needs to be inspected and fixed. They are also concerned about the damage that the trailer body sustained from hitting the highway.
We have NHTSA involved and I have talked with insurance. My insurance company wanted me to attempt a fix with the manufacturer first before submitting the claim as they feel it is 100% a manufacturer flaw.
