My only suggestion is try it first ! Rent an RV, go some place close for a weekend. Then go a bit farther for a week or two. Big change in lifestyle. You may not like it, some don't jump in the deep end of the pool !
While a Class C or Class B+ may look good, they are very small and can be very expensive. Personally, I would get a smaller trailer (24' or even 20'). It gives you the option of parking it and taking a day trip somewhere nearby.
You are new to the whole RV lifestyle, so you will learn quickly that you need to be a handy-man. If do not plan to camp where it is below freezing (except in an emergency) then consider not having a furnace or propane. Induction cooking and microwave/convection oven work well, but require you to be plugged in or have a generator. You will also be happier with a compressor style refrigerator. Most people just use residential models, but there are one that run directly off the battery.
