cannot imagine renting a car could be cheaper than using your own, even with higher cost of towing. As far as Uber, doubt it would be readily available in non-urban or suburban areas. We live in a part of Va called the Northern Neck and there's nothing but one's own vehicle available to go anywhere. The wide open spaces of the West would seem to be even less likely to have ride share services. We have been RVing for almost 45 years and I cannot imagine NOT bringing our toad on a long trip, particularly one where our goal is to wander and see this great country! Thinking if you already are set to tow, why not do so? Once you get west of the East Coast, there are far fewer toll roads as well, so that expense of towing an extra vehicle would not exist. Just my thoughts.
