Insurance wise for a van that you convert on your own, it would be insured as just a personal van. Whatever cool stuff you add to it, the average insurance carrier will not consider it should your van gets damaged, vandalized, stolen, etc. So if the van is worth $2,000 and you put on $5,000 worth of extra stuff, it's still only going to be reimbursed up to $2,000 or less. There are some provision for extra coverage on a bigger stereo system and maybe rims, but you'd have to pay extra for that. There's Specialty Vehicle insurance, where you'd get your van appraised for all the vandwelling addition and the carrier will charge you extra based on it. But it's not going to be cheap.
