Bought a used 10 yr old Charmac 4 place enclosed 2 years ago.
Granted the trailer was basically new, like had factory grease in the hubs that still looked new and literally 500 mi on it.....if that.
The trailer did however sit outside in Portland for its entire life. PO re sealed the roof seams about a year earlier, looks like may have been one small leak judging by the roof paneling inside.
Aside from some minor oxidation of the corner caps, the trailer withstood the elements great.
I've put a couple thousand trouble free miles on it, pulls great, solid construction all around. Even the brakes work great after sitting that long.
Was skeptical about giving up the quality of my previous 2 place Triton that I beat the living tar out of for close to 10 years, only replacing tires and packing wheel bearings but the Charmac is a great trailer in my book.
Best of all, it was about half price of a new one and about 1/3 the price of aluminum frame equivalents. I can buy ALOT of extra diesel and rattle can spray paint for the frame for what it saved over an aluminum trailer.
