Costs of things

During our 40 years of camping; recently in a used 30 ft. Class C, we have always been cost conscious about everything from the purchase price of the RV to campground fees. But after totaling up the massive amount of money we've spent on this 15 year old MH over 7 years just on repairs, etc.(actually the depreciation on it isn't too bad) I think we need to put some costs in perspective. For example whether we pay $15 or $35 for a night or spend an extra $100 on gas it's all peanuts compared to all the costs of the motor home. Next time someone tells you how cheap they can travel in an RV, tell them to add in all the cost referred to above.
