The camper has been stored inside since new (excluding travels). However, we sold our large shop in the spring... I don't like storing things outside. Even our dump trailer has been inside since new!
Our commercial warehouse doors are a bit short. But I figured we could get the camper inside with a custom low profile rolling platform. Massive 8" caster wheels with kingpin, ball bearing and steel center.
Worked perfectly. Now the camper enjoys 78 degrees.
Donki (the F250) has also been garaged since new (except travels). It really starts to show after a few years! We recently sold Faith's 2021 Tacoma; the transport driver thought it was new! He didn't believe it was a used truck until we showed him the odometer.
Just shows you can use things. And if properly maintained they can last a LONG TIME!
