Possible frame weld broken on new Montana

I talked to the one who is scheduling the return trip today. Actually the unit has to be at the dealer on Feb. 6th for them to pick it up on the 7th. The scheduled days to work on it are the 15th-18th. Everything has to be out of the unit. They were more worried about the AC units not cooling the unit than the flex!!! I finally asked them how in the world would they test the AC units in FEB?? She said it was easy to do. :-huh:-huh Then the unit's side will be fixed as well as the inside banister and right rear skirting. The unit will then be sent to the "rain bay" and tested for water leaks with the slides closed, then open. If it passes, it will then be thoroughly cleaned and then shipped back.
They will be emailing me the steps I have to do to ready it for transport. I'll pass the unusual stuff along if there is anything. Just wanted to update you guys.
