Spoken like a true salesman. I'm thinking the ceiling will drip or the rug will get wet, and then I will go fix the leak, oh, but I guess its better to have the side wall absorb the water until the fiberglass seperates from the substrate, now you're screwed. I'm not saying all, but honestly, ALOT of them are.Sad.
I have owned stick and tin trailers in my younger days, and many of the older stick and tin trailers are still around. Airstream..its estimated 70% of all of them EVER made are still on the road. I'm just saying!!
