Here is a link to a great article in Motor Home magazine that goes over all of the pertinent facts an RV motorhome owner should know as they go through the process of deciding whether they should purchase a Tow vehicle, and if they do, what do they actually need in addition to the vehicle.
It’s a well written article and I recommend it as a must-read for anyone considering buying a tow vehicle.
