M139: Ext. & wall construction? Hairline cracks on exter
Just bought a 2004 M139. After getting it home from a dealer's lot (this dealer has an excellent reputation in Phoenix), I've got some concerns after more investigation and need to address these concerns as quickly as possible.
Can anyone tell me:
• What the exterior of the trailer is made of (obviously not aluminum)?
• What is insulating the trailer walls (foam, insulation, etc.)?
My first concern is the front of the trailer has some dents/dimples in the exterior. Nothing major, not pretty, not anything I care about. But a friend told me that because there are some very minor cracks in the surface of the exterior, it probably will leak into the wall area. Being in Lake Havasu City, AZ, it rains about 6 times a year. Usually in August, usually when it's 110° anyway, and everything dries instantly. We don't deal with a lot of dry rot out here. Is this something I need to be concerned about? Is there a fix to the exterior surface of the trailer (i.e. coating like when you re-coat a redwood deck) or anything I should be aware of?
My second concern is that the foamy insulation stuff around the exterior edges of the trailer is brown and brittle. I'm thinking, that's really not a big deal, I can easily re-caulk (or whatever is the proper material to seal this) fairly easily. Am I correct in this thinking or is this a sign of something major down the road?
The very reputable dealer stated that they went through the trailer with a fine tooth comb. They informed me that the refrigerator doesn't work on propane (which I don't care about) and that the fan in the bathroom has a broken blade (which I don't care about). They also found a leak in the black water tank and they have fully repaired the tank (which meant taking out interior walls to remove the tank because it can't be dropped through the bottom). They did a lot of work on this TT before they released it to me. I'd reasonably assume that if the trailer leaked they'd not be selling it.
