we started RVing in 1986 but didn't pull a toad until 2003. for the first years we simply dud our day trips in the RV and we became pretty accomplished at breaking and re-setting camp. after 10-12 years of that we rented cars, mostly from enterprise and that worked OK. it was a hassle even though they picked us up.
we made the decision to start towing in 2003 and bought our first jeep...a new jeep wrangler sport (which we still have) and boy did a whole new way of RVing open up to us. we were free! if we wanted to go out for dinner on an overnight stop we could. no more breaking camp. no more waiting for a rental car and the hassle involved. after a while it got so that I could unhook the jeep in 5-10 minutes and hook it back up to the MH in about the same time.
if you take a lot of RV trips or if you're out for weeks/months at a time then I say start towing. to me, renting only makes sense if you take 1 or 2 trips a year.
good luck.
