Very cool you've got those thoughts. FWIW, my lottery fantasy includes taking an armored truck to the chop shop and converting it into a tailgate/road trip rig. It would be a tweener between an RV and a Hummer. It's gotta be dual use as a tailgate vehicle and something with some offroad clearance that would allow for an escape into the Canyonlands Maze and down any forrest service roads that you could take a 4wd pickup truck.
The list of features would include side panels that open up with a flatscreen and bumping sound system, a tap or two, a charcoal grill set-up, a gas top range and sink, a genetator, a fridge, storage for all the gear, a satellite box, a pop top, and a hydrolic back door on a bottom side hinge that serves as a ramp into the vehicle, or a tailgate platform sturdy enough to stand/sit upon. Inside would be a mancave with a couch/bed that is comfy for 2 or 3 on a rainy day.
The paint theme must be multi-layer glossy black like on a Lexus, and trimmed with gold. The Ralphie logo is incorporated, leaving no doubt as to fan allegiance.
It could be done for under $150K, that would work, and done well for $200 large.
The base vehicle would be along these lines.
