I use RV Park Reviews also. Great resource. You can use Google maps by centering on a town and typing "RV parks" or "campgrounds" in the search box.
Ask the RV park if they allow a multi-month stay. Some don't. After you tell them the size of your RV, they should know which sites your RV will fit in, but ask if there will also be room to park your truck at the site. Make sure your sewer hose has the end-piece that makes a secure and sealed connection to the hole in the ground. You cannot just leave your sewer hose dangling in the hole for 6 months. So get something like this if you don't already have it:
