If this is a major problem, and the dealer knows about it now. They realize they accepted a crippled RV and would want to get rid of it fast (make it someone else's problem). If they new about the problem before accepting it, then they probably got a good discount on it.

I would want it checked out. What does the frame look like from inside the battery/hydraulic compartment? Take a picture of the weld and the area around the suspect are in the compartment, climb in there if possible. If the paint is flaked or cracked at the weld that would make me believe the weld failed.

This could also be just an item between the laminate from the manufacturing. The way these things are thrown out the door now, i would expect this.

Im with DutchmenSport on this, throw it out if in doubt like they did at the factory.

Im not an expert, just my 2 cents.
