Eric,
When the guys on this site are talking about a motorhome they are talking about a class 7 or 8 truck with motorhome (same as toter home) but bigger with either a class 5 hitch or a 40,000 lb hitch. I haven't driven one yet but they tell me that you pretty much don't even know if the wind is blowing till you get out of the truck. Even the Motorhomes can pull a Stacker fully loaded with a couple or 3 cars inside.
Check out
www.kibbi.com or showhaulers site to see what these things are about. As far as I can tell I don't even think the bus class motorhomes come close. The only real difference between the toter and motorhome is the hitch and size of living area. Basically a toter with a 13' living area is on the same truck as the 22' motor home. Just one is set up for the 5th wheel and the other uses the biggest ball hitch known to man. 40,000 lb hitch looks like it would pull a battle ship!
