Big steve, you're running the gamut here on RV types. Based on your questions, you don't have much if any experience with large vehicles, towing, etc.
If that assumption is correct, or even if incorrect, first think about "how" you plan on using the RV.
Touring the country weeks or months at a time? Few trips to the state park up the road a year? Destination camper, go somewhere, park the RV and stay a while? Driving to get somewhere (main highways/freeways primarily) or like to get off the beaten path (county roads, forest roads)? Terrain, driving around the flat part of the country or headed straight up the side of the first mountain you see? Bringing a golf cart/wheeler/SxS or bikes?
Once you've decided how you plan on using the RV, that will help decide which type offers the most conveniences and least downsides.
Back to your actual question, I'd finger out if you're comfortable hooking a big trailer, any type and taking off down the road, rush hour traffic, backing into or out of tight spots. Bumper pull or 5th wheel both require some skill that you'll have to acquire.
