Julie,
You can get by with a vehicle that has a V-6 engine, automatic transmission 
with auxiliary cooling. The vehicle MUST be properly equipped to tow the 
weight of the Rhodes. They are rated by GVWR (gross vehicle weight rating) 
which is different from GVW (gross vehicle weight). GVWR includes the 
vehicle, occupants, a full tank of gas and the vehicle to be towed. The 
higher the GVWR, you get additional things like better brakes, tires, engine 
cooling and a rear axle ratio for towing.
A good truck (SUV) salesman can tell you what type of vehicle you need. There 
are differences in V-6 engines in horsepower and torque. I tow with a Dodge 
Ram 1500 pickup with a V-6 and automatic. The transmission has a lockout 
(electric button) for overdrive for towing. I have a class 3 hitch.
I also recently put new Michelin tires on with a Class E weight and 
temperature rating. Tires with additional weight on them such as pulling a 
trailer generate more heat. 

Rummy..........I wonder if the Vikings will win a game this season. Go 
Packers.
