Most of your pics showed up sideways - there seems to be a lot of that going around, so don't feel too stupid for it.
Nice looking rig! Year/make/model/length/engine/transmission? If I read the picture right, that's the first time I've seen "factory" insulation on the frame under the floor! And someone did a right good job of insulating the body, too. You have a great start!
If I were you I'd keep the paint job.
Do you have a genny? Most bookmobiles seem to.
Welcome to the madness!
