to insulate under the truck see if you could get a spray foam guy to spay the hell out of it after you have finished everything on the inside, run all your wires though bigger pvc so the can be pulled or added to later, unless you want to try to dig through the spray foam, I would think they would do it for a couple hundred dollars if you drove your rig to their shop after hours.. ?
