I find it amazing to watch a double/triple tow flip over. We've seen it happen a few times. Everything looks like it is in slow motion when the things go airborne. We would only do it in case we had to leave in a hurry due to a disaster (fire or hurricane) and we would not be moving very fast either. Ofcourse we no longer have to haul the food cart around with us so we do not need to triple tow.
We tow a 5,500 lb Jeep Grand Cherokee with our BlueBird FE (40 ft). David says you can't feel it back there. We use an older Stowmaster 5000 towbar that is rated for 6000 lbs (I think the newer ones are only rated to 5000 lb). David didn't feel it when the Jeep blew out a front tire and dragged it long enough to chew up the fancy rim (
) before I could get him to pull over (I was following in the old Class C).
We have added a 150cc touring scooter to our mix and will stick it on a hitchmounted motorcycle rack mounted on the back of the Jeep.
Many campgrounds will charge you extra to store your car trailer or a dolly. We thought about buying a pickup truck and putting a flat bed on it so that we could haul a trike. We got the scooter instead.
