You may well be "crazy," but it likely doesn't have anything to do with considering the RV lifestyle.
Our full-time lifestyle has cost us exactly $24,695.46 over the past 12 months. Here's what's included (major categories - I'll not detail the little stuff):
Entertainment (satellite TV & data for internet): $2,140
New hitch (traded trucks): $1,052
Laundry expenses: $342
Mail Service: $447 (also provides our legal domicile)
RV parks & campgrounds: $9,137
RV (Including payments of $4,168, insurance, mods, improvements, maintenance & repair): $6,287
Tow vehicle operation (including insurance and fuel): $2,458
Utilities (electric where metered, propane): $380.
I do not count food, toiletries, health care, etc., since those are all expenses we would have whether we lived on the road or not. Only you can decide what will or won't work for you. A couple of good places to start reading are:
Escapees RV Cluband
RV-DreamsHoward on RV-Dreams posts all of his budget info and has written a LOT about what you need to know. The Escapees RV Club is one of the oldest and largest in the country and is comprised largely of full-timers. Lots of good folks willing to help both places. Bottom line - there's a lot more to think about than just whether or not you can afford it.

P.S. - We've stayed in several RV parks in New England that had live entertainment on Friday and/or Saturday night(s). They mostly drew on local talent, though (and there was some
really good talent, too).
