I really like your idea. When I built my mutant vehicle with a lift I made 2 mistakes. 1) It didn't look mutated enough to make DMV very happy even though it was 75% custom built. 2) I put too many obstacles on the deck and eventually there were only a few spots for wheel chairs.
Mutant vehicles need to be radically mutated!!!!!!
I would build the entire passenger area in such a way that it was an open flat deck for good wheeled maneuverability. Have folding chairs that fully ambulatory people can get out and place where they want and then stow when not in use on rack.
A thought occurred to me when I read this thread. Pull a deck over wheels flat bed trailer or a hay trailer with the Military truck.
Then install 2 lifts. One on the back of the trailer and one on the back of the bed of the truck. That way people could board the trailer and then if they wanted to take another lift from the trailer up to the truck bed for a better vantage point. The lifts need a very sturdy place about one foot by four feet to bolt down to but that is not difficult to accomplish. The commercial wheel chair lifts all have a hand pump/release backup incase the power goes out on the vehicle so no worries about power outages. When the lifts deploy to the ground level they stretch way out from the vehicle so there will be a nice reach out away from the trailer and with the correct measuring and trial with a lift you would be able to see if deploying the lift from the truck to the trailer deck would work well. Both lifts if not already equipped could have micro switches installed on the bottom of the lift to interrupt the lowering circuit so that the lifts automatically stop once they encounter the ground or deck. This would save on wear and tear and make operation by the neophyte user easier.
When thinking about mutation I would start with what you want it to look like at night and really go for the lighting effects. Once you have that concept you can flesh out the day time appearance between the led rope and el wire. I think the most effective mutation is a facade attached to the outside of the stock vehicle with lots of light and mural with some 3d elements. Wire frames work well for shapes that are present when illuminated only.
The good Captain Goddammit likes to espouse the greatness of the add on alternator for powering all the 12 volt things. He is much more an expert at that than I but his suggestions in that area make me think..... Possibly one of these simple one wire alternators could be added to the accessory system at the front of the engine. With proper mounting and a longer belt perhaps a 12 volt alternator could be added for the purpose of charging a deep cycle house battery that would run the lifts and some other 12 volt accessories.
Gov Liquidation dot com is a great place to look for military trucks. I believe there is a base near you where they become available from time to time. Definitely do not bid until you have looked at the truck and completely understand what it needs to function normally. You can get a turn key truck from time to time but it seems to me there are allot of starts with jump or does not start/operate auctions. Its good to know what you are getting in to before you bid. Expect to have to do a full service changing of all fluids and lube.
Good luck with this. I like the idea very much and your enthusiasm.
