It's hard to tell from a few pictures. I noted some body damage on both sides. More concerning to me is that I see what appears to be the bedroom roof A/C interior bezel hanging down. Can't tell why, but one would certainly want to check the reason for that....hopefully not water damage from leaking around the A/C that caused whatever holds that bezel in place to rot out.
Without a thorough examination of the unit it's hard to give advice on whether it's a good buy or not. Looking at NADA it shows the 2001 Monaco Diplomat Average value at $24,900. At $7100 over that, one would certainly hope that the seller has plenty of room to go down.
