Well...with respect to jefe4x4 (truly!)
I'd say the Lance is. Or at least was. Time will tell with the new one.
122 months is 3700+ days. I doubt if I spent 50 of them elsewhere than my camper.
All kinds of weather. A couple of Colorado winters (winterized, water from jug), Arizona desert, Texas Gulf Coast, west Texas.
NO problems with the structure, nor Lance's work.
A few issues with appliances, more lately, which is why I traded for new.
Seemed like time for a handier man than I to own that camper.
I bet he will love it.
