I agree with AZAspect with one proviso. We are long term motorhomers who rented a CruiseAmerica 30'er last year while between rigs. CruiseAmerica has their motorhomes custom built to their "lowest common denominator" specs. Renting one of those is not necessarily representative of what you can buy. (No tv, no steps, no rear view camera, small water and holding tanks, small house battery, limited storage, etc.) El Monte and Roadbearrvs Rvs seem to be a little more upscale from what I have seen in the parks, but I have no direct experience.
We are in California, so those brands may not be available where you are. Rent and then compare...
