If the latches are pulled out of the wood that they are screwed into, that might be another indication of wood-rot. If the latches are just "Broken", that's something else. The more I read over your discription, the lower my opinion gets of this trailer.
Get the "date code" on those tires.......somehow....I'm skeptical about the "2 years old" tires.
It's a 3-way fridge......make darn good and sure that it works on
propane. That is one expensive fridge......
WE NEED PICTURES........
$8,500??????? surely he's kidding.......you can buy a California or Arizona trailer that has no rust or all the other issues that you mention for that price.
Trust me....that laminate (if it's the factory laminate) does not just peel up around the edges. That suff is very well glued down. I've never seen a TM with peeling (factory) flooring.
