Hi Maria,
I'd suggest looking for a good used Class C, rather than renting. If you decide RV'ing is not in your blood, then it would be easy to sell it.
Renting for a short time is not going to help you decide.
I've been Rv'ing since 1956, and now as an adult for the last 12 years doing at least 60 days per year, but when I went "full time" Oct 2, 2013 it was a REAL eyeopener for me. (translation I thought I was ready, but there was a steep learning curve.)
Regards, Don
My ride is a 28 foot Class C, 256 watts solar, 556 amp-hours of Telcom jars, 3000 watt Magnum hybrid inverter, Sola Basic Autoformer, Microair Easy Start.
