Probably the easiest fix of all to problems with the old trailer, make them someone elses.
Congrats on the "new to you" trailer (I can't imagine owning one for 6 years and using it 3 times but I know it happens). Maintenance overhaul should let you enjoy this one for years. I agree, double check that hour meter though, mine had 2/10's on it at delivery just from being test fired.
I like the interior finish!
Don't take life too seriously, it's not permanent.
