I think it really depends on how you will be vacationing with your motorhome. If you plan on taking your motorhome to a destination and leaving it there for multiple days, then having a tow or rent vehicle is necessary. If you have a car at home that can be modified to tow, then do it. If you plan on using your motorhome to take vacation tours, meaning that you do not plan on staying somewhere for more than one or two nights at the most, then you may not need a tow vehicle at all. For me, I would rather leave the tow vehicle at home, but will take it if I feel like I will need it. I just got back from a two week vacation in the motorhome and did not need an extra vehicle at all. We also did not stay in one place for more than two nights at a time. Towing is no problem. Would advise you to modify one of your vehicles to tow. Renting is too much of a hassle.
