Years ago, I bought a 2015 Ford Transit, LWB, extended body, tall roof. I used it to move my belongings from Idaho, back east, to be closer to my chiren after I retired. I planned on building it out as a class B camper (I am a wood worker). But too many quality problems with it, left a sour taste in my mouth, so I never did so.
Long before throwing in the towel, I bought 50 or 60 lineal feet of 5β wide, 1.5β thick automotive (and marine) insulation(the brand name escapes me), and installed it in the walls of the van, underneath the plastic cargo sheathing. It made driving it MUCH quieter, no longer sounding like I was in a bass drum, and made it much easier to get cool in the summer. I still have a significant amount left over.
Though I have NO complaints about the interior noise level when driving Miss Daisy, I am considering installing it in the roof, and doors, to add an even more insulated feel to Miss Daisy.
