Do you have to be rich to own and to use a Class C ?
You'll need a minimum of about $10,000 to buy one that is in a useable state.
About 5 years ago we paid $7500 for our 1990 Winnebago Warrior. Right off the bat we had to put $500 into the generator, $1000 into tires, and $500 into the cab air conditioner.
It also had leaks in the roof, and has a mold problem which doesn't bother anyone in the family except me unless I take Allegra, then I have no problems. :)
The leaks had damaged the shower walls, so I ripped out the shower and rebuilt it. Probably another $500.
I've put a few hundred into a blown heater core, and $500 into replacing a water pump.
We probably would have been better off buying a $10K RV, but we didn't have 10K, so it is what it is.
Class C RVs get 8-9 MPG. It costs me $90 a month to store it, then there is insurance and roadside assistance. I use it about one weekend a month on a 2-hour trip. 142 miles one way, or 280 round trip. At $3.50 per gallon, that's $108 per month. Camp sights are about $20 a night, or $40 a month. Typically when I or the family go camping we make a special grocery store run for sodas and snacks and goodies for the trip and that's easily another $100.
So you are looking at a bare minimum of $300 a month, or $3600 a year just for simple weekend excursions once a month. That's more than my car payment each month.
So. If you are going to go camping in an RV once a month plan on spending $350 a month to do it. Even in the months you don't use it, it's probably going to cost you $150 a month just sitting in storage.
If you can't afford that, it's too "rich" for you. :)
