Triple Towing
Question: Can I tow a 3500 lb. Cherokee with a 12' UTV trailer and UTV (1800 lbs. total) with my 37' diesel Motorhome? The motorhome weighs 22,000 lbs. loaded. GVW is 29,000 lbs. I have a 7000 - 8000 lb. hitch on the motorhome. Tow bar is Blue Ox, 10,000 lbs. Overall length is 66'.
Answer: On the surface,it sounds like you should be okay from a weight perspective, but please double check the complete set of RV Weight Definitions: http://www.your-rv-lifestyle.com/vehicle-weight.html .
In particular, see the distinction between GVW, GVWR and GCWR.
Aside from whether your weight and capacities are in line, you should consider the regulations associated with overall length of the combination and triple towing restrictions.
Below is a link for the ever-popular question about triple towing. The gist is that it depends on the state. You have to look at each state that you plan to travel through and determine what the law says about triple towing. Some states allow it some do not. There are maximum length limits per state so you have to be cognizant of that limitation.
