Update from OP....took the TT back to the dealer for the drawer stop and a few other punch-list items...turns out the drawer DOES (and always did) have a stop...but it didn't catch, because the work at the assembly plant was so slapdash that the drawer rails weren't properly aligned...
soooooooo, for lack of the most easily accomplished QC check--simply pulling the drawer out and pushing it back in, which would have revealed the need for minor shimming/realigning of the rails, the factory sent out a product with a (albeit very minor) defect...that led to my raising this issue with the dealer (who corrected it)...with this and the other issues mentioned, I ended up having to take hours off work to go get the trailer, drag it to the dealer, and then do the whole process in reverse when the work was done...(please, no 'you should have caught this at PDI'...I didn't check the toilet handle to make sure it was attached correctly, either, during PDI---there's just some things that should be able to be taken for granted)
In my estimation, it would have taken no more than five or ten extra minutes of checking and adjusting on the factory floor to make sure the drawers worked and the television-attachment panel was set securely in the wall, and to correct the other little shortcomings that have ended up costing me and the dealer a whole bunch of time and causing a whole bunch of aggravation
