This topic has come up many times in the last 6 months and is a true YMMV.
For us, we use both Harvest Hosts and Boondockers Welcome (now the same company, but keeping things separately). We've only full-timed since April, but have gotten our moneys worth. We normally use Boondockers for a one or two night stop while we're going from point A-B. We've had multiple stays with both, and every experience has been very positive. We prefer Boondockers because most places we have the option to stay multiple nights, and many have hookups. We just finished a six night stay in Centuria, WI at a 'hobby farm'. Super friendly folks, 50 amp power, and water. We visit an aunt in Luck, WI., just 10 minutes away. We're already planning another trip next spring.
We have a five night stay near Pensacola reserved with a Boondockers. Full hookups (dump on site but not at campsite). Most Boondockers Welcome sites that have hookups do ask for a donation, usually $5-$15/nite. More than worth it.
