Congrats & welcome......
Mainly look for things that are not right or don't work. We have a 2013 Puma 356 QLB & only been back to the dealer for a curtain issue (curtain that covers the garage sliding door window.) & the remote for the stereo did not work but think it was more operator error.
We have owned two Pumas great trailers for the money. Not alot of issues hopefully will be the same for you.
