I traveled full time over 5 years in a Class C without a toad. I occasionally rented a car, but had no problems without one. Instead of staying a month somewhere and using a car to travel lots of miles, I planned routes that took me to all those places and actually put on less miles and therefore didn't cost me more. I ended up getting a toad because of the workamping jobs I was taking.
That said, I, personally wouldn't go the tow dolly route. A friend did to use the car she had and only made it work because she put a hitch on the car to move the dolly around. She had hooking up the dolly etc down to a science, but as we were doing so in the rain one day, I was hooked up and sitting in my rig while she got soaked for an additional 10 or so minutes finishing up. We had started at the same time.
But many like them. BTW, my car is front wheel drive and towable all wheels down. It's just a matter of the manufacturers making it do. Honda was doing so for several years. My car is an older Chevy that I purchased off eBay in 2010. It's 16 years old now and an insurance claim for hail damage last year got me add much as it's worth... so when I sell it eventually, I'll make money lol.
Ok, I went way off track, but my mind does wander
