We traveled for several years without a towed vehicle. We used Enterprise often where we needed to have a vehicle to get around at our destination. The only problem with that is, there's not always an Enterprise conveniently located at all destinations (although they do have a pretty good network of locations).
For the past couple of years now, we've been towing DW's 03 Explorer, and wouldn't be without it. Even on trips where we didn't expect to need a vehicle, there are unexpected needs that sometime arise where we were glad we had it along. For me, there is piece of mind to having a toad along while onthe road, and that is having YOUR own vehicle on hand should the unfortunate breakdown ever occur with the MH and it needs to be towed in for repair. Would save a lot of headache of trying to scrounge around for a rental vehicle in an unfamiliar or not-so-populated area.
