We have no slide outs and although there are just the two of us it was a shame to not use the garage . I came up with this idea from looking at the toy haulers that have a bed that goes up above when traveling with your toys.
I built a sort of elevator system which is steel gas pipe put together as a frame then a platform a winch from Harbor freight got a futon from our daughter. when we travel I raise it up to the ceiling block it so it stays there load the bike and off we go. When we are camping for extended times the bike stays out side and the futon comes down so the whole garage area is our living space. Add the TV, a throw rug, and we have a whole other room.
Works for us.
