I got another bus yesterday to toy with. If this keeps up, I might have to join a support group.
The floor is totally rotted out and the interior is crap, but the mechanics and exterior are awesome.
My first bus has junk engine/tranny, but a decent floor and body inside and out.
I'm trying to inspect what I need to do to cut and weld to replace the rusted out metal.
Can't swap engines - one bus is diesel and the other's gas.
If you're at all serious about the weather, you gotta insulate and caulk. Otherwise, why not just get a pop-up?
