As full timers, we figure the average RV park costs about $30/night or about $900/month. (yes, I know you can get monthly rates) These RV parks offer nothing to our lifestyle except we use them about every 2+ weeks to dump our tanks and fill up our fresh water. RV parks are just full of negatives like dogs, noisy neighbors, smells……….. The savings from not staying in RV parks, we used that money for solar. We’ve been on the road now as boondockers for 10 years.
