3 days after sitting in my driveway loading it, noted the SLIDE FLOOR was separating from the SLIDE WALL when retracted! Ouch. You can see the aluminum U channel still attached to the slide floor with the wall lifting up over an inch or more! Dealer took it in to fix since it came with a 30 day warranty. Anyway, says a weld broke and they are re welding it. Does this sound legit? Service guy said to ask for a warranty on the fix for like a year. What do you think?
