Was just on the Forest River forum explaining to a toy hauler owner how to do a blower door test on his unit. He posted he could not see anything that looked like water intrusion but the unit had a damp, musty smell near the side entrance door.
Candidly, most people don't know where to look and what to look for. You have to be a 'detective of sorts to find intrusion and if it's progressed to the point where it's showing inside the unit, or you can smell it, it's bad.
If I was going to buy a used unit (I'm not), first thing I'd do is lift the bedding and look underneath in the nose of the bunk, open the side cabinets and look in the bottoms where the wall board ends in a seam with the bunk floor and use an IR thermometer to scan the walls and ceiling. Mold causes heat.
Feel the interior walls and ceiling (again around the nose area). If the interior walls are soft and spongy, you have an issue. If it's not your camper, be careful not to poke a finger through the wallboard because all that is probably left is the paper covering, the wood behind the paper is long gone...
I suspect the guy with the toy hauler never did his seals and he's about to find out what a nice warm dark atmosphere and water soaked wood and insulation can do. I bet the water came in around the door frame and I know I don't want to fix it.
Not limited to TC's at all. Any RV can be impacted, even MoHo's.
If you have a mold growth situation and if you get into remediation PLEASE wear a mask and gloves when pulling out the impacted wood and insulation. Some of that stuff is very toxic to breathe and can cause skin issues too. No point in winding up in the hospital and having a moldy camper too.
