My dad owns a co-op airplane, it was the only way he could own one. In that situation the airplane is owned by a licensed corporation and all 5 guys are officers of the corporation with equal 20% stakes. When you want out you sell your shares with the permission of the remaining owners. There is a secretary (one of the officers) who schedules the time usage and collects the monthly dues, uses that money to pay for annual services and space rent at a local small airport. If an arraignment like that could be made I might be interested. Except for the whole bed thing, maybe I'm weird but I don't like hotels and I don't like sleeping in other people's beds.
My brother is a CPA and took that idea further and formed a club where the members have the ability to use a Class A rig (2005 Fleetwood Discovery) , a monster Jeep, a boat and a set of 4 quads. Buy in is 25,000 and monthly dues are around to 350-500 to cover maintenance, storage and insurance. He as the club founder owns all the toys and credit checks are required to join. He replaces the toys semi-regularly and in the end it doesn't really make him money, but he gets access to more and nicer toys than he could otherwise afford. I believe the club has a maximum of 10 or 15 members, and if you find someone to buy out your membership you get 25% of the initial fee's back. He is constantly watching auctions (His father in law is a GM at a car lot so he gets to go to auctions.) for just the right replacement toy. There is talk of added Wave Runners to the club but the members have to agree to an increase in dues. There are also tons of rules, about how long for each use what happens if the item is returned dirty and stuff.
I wasn't interested in my brothers club mostly because the motorhome was my key interest, and I'm not fond of sharing! The other thing is I don't think you can have more than one item at a time so you cant take the boat to the lake with the motorhome. (Unless you are my brother who does that all the time!)
