Here is something that was amiss on our Accolade 37K. At the delivery walkthrough, they extended the dinette slide, there was a huge jolt and bang.
The dealer guy just shrugged his shoulders, "I don't know what that is."
When we got back to the place we were staying, I found this. The stop tab that limits the extend travel, at the aft end of the dinette slide was hitting this black tank support bracket.
I was unwilling to let the so-called "techs" at the dealer try to fix it, besides, we were staying in the coach and weren't about to let it sit on their lot for who knows how long. I bought an air die grinder at Home Depot, and it took me about 20 minutes to crawl in there and grind some clearance in the bracket. Checked all the bolts holding the bracket, no other damage. The bracket has a little bend in in it, but otherwise OK.
The only other damage was a gash in my arm from a sharp end on a tie wrap. Trimmed that properly...
Problem solved...
