1 man flip over in car
Another option if you want to be portable would be those shacks that fold flat, 'minute man' type. Pop them up and put in a center pole to keep it open. Fairly cheap, light, and you can move it if you want yet. Just doesn't have the sled base so you'd need a sled yet unless you can bungee strap all the gear on top of the shack to keep it from falling off.
