Are there any models out there that you can tow a small 2-quad trailer behind without voiding the warranty on the frame? I've thought about that as well. I'd rather put them all inside though under lock and key. It seems that even with a vapor wall there should be something like a ramp on the front wall where you can get the first two semi-vertical to leave room for the second pair behind them. Even with a 12' garage I would think this might work. I don't know if the vapor wall would be strong enough to handle the added pressure and weight though

.
Most with a vapor wall and garage have a lowered ceiling becuase there is a bunk over the top from inside the RV section. the lift and possibly the standing on end would not work with these models.
here are a couple ideas. if you have adult and child size four wheelers you can strap boards across the racks and stack the child's ATV's on top. we do this for my brother with his sportman 500 and 50cc yamaha and works great.
Another point. lets be practical here, unless you keep the atvs inside while camping the vapor wall is not that Important. When we get to where we are going we kick out the bikes and quads and let down the sofa and dinette until its time to leave. turn the gas off while towing and store your gas cans in the truck bed or beside the RV when you make camp. pack it up if you leave camp for the day. Its not that hard to do.
this was problem we had when looking at a TH'r. the fifth wheel units are primarily designed for a mom and pop type camping with an ocassional guest. (one master bed/bath, one loft bed and then its sofa time)
I'd suggest you hit the RV shows and take a look at everything you can first. floor plan was the biggest topic for us to decide on. we have three young kids and needed to maximize both sleeping and gargo capacity. just wait until each one wants to bring a friend
We can haul 16ft of whatever you can fit into it and can sleep 10 people in beds and we have a ramp room to pick up 2 more person's sleeping capacity. That's 12 in beds. The bath is central to the camper, not in the master suite too.
(family of 5 +3 friends=8 add my brother and sister in-law, thier kid and 1 friend=12)
I'd say my biggest disadvantage is that I have a 30' bumper pull. but I havent not been able to go where I wanted yet.
we were just at the St louis RV show and the new 5th wheels are still the same problem just have 2 and 3 slides now. That garage kills it for large families!
