One of the financial advantages of traveling in an RV is not having to eat every meal in restaurants. Even when we are on the road, I buy a local Sunday paper, cut out the food coupons and take advantage of the sale items. Look for the free and low-cost attractions available to RVers. We recently visited the Kennedy Space Center in Florida. Parking was free and there was no admission charge.
Factory tours can be fun, fascinating and free.
Museums, parks and flea markets can provide low cost ways to spend a day. You don't have to spend a lot of money to enjoy yourself. But you get the picture. Once you are past the expense of purchasing a rig, RVing can be a relatively inexpensive pastime. I spend summers in North Carolina and winters in Florida.
