skip1h, welcome to iRV2.com. We are glad to have you join us here and look forward to being able to help answer any questions you have. I think first you will want to know what kind of camping or RVing you will be intrested in doing. Once you have decided you might want to rent a unit and see if it fits the bill. Example: the 21' Toyota may be fine if you are not going to leave the flat lands of Fl. If you venture into the mountains you may no be satisfied with the power or you my find you need or want more room. Good luck and have a great summer.
