Interesting home-built RV

That's really cool. What do you tell the campground reservation desk when they ask you for the year and make of your RV?
I guess tell 'em it's custom, but with a capital C.
"We have a 2018 Caboose Custom with the specialty exterior paint and equipment pacakge ..."
Given all the bazillions of brands and sub-brands in the RV market, it would be easy to believe over the phone.

Quoting George Costanza; it's not a lie, if you believe it. 😉
I wonder how he registered it, as the old camper with the vin and frame? How is it listed with DMV? Insured?
