We did our first long trip (6 months, 6000 miles) without a toad. We didn't have a car you could tow 4 down anyway. We rented from Enterprise when we wanted a car. Getting parts for the RV got real expensive :)
We found that we were picking campgrounds based on the proximity to an Enterprise office. Not the best criteria. They say "we'll pick you up" but there's a limit as to how far they'll go to do that.
The next year I set up to tow a car. First thing I needed to do was find a good toad and buy a tow bar and brake. I lucked out on the tow bar, an older gent was selling his Blue Ox and RVi brake 2 for $900. A few hundred more to wire the Eqiunox and we were off.
We found that we see a lot more stuff with a toad. We did our second long trip out towards Glacier and we would have been hard pressed finding a rental in N. Dakota.
