I'm sure you've gotten a lot of responses by now. You can rent RV's. Not sure of websites, we have our own, but you can always google DFW RV rentals and see what pops up. There are 2 great places in & near Arlington to go!! Both are at Joe Pool Lake. You can go to the Joe Pool Lake State Park in Grand Prairie I believe, that's a nice one, and the other is off of 360. I think it's called ....Lynn Park. It's a private day/camp park and it is a very nice one too. My in laws go to one or the other for 50% of the summer. Another nice place to get away is about 2 hours from here, Possum Kingdom Lake State Park!! We went there annually as a child-teenager, and I loved it! At dusk deer come out, and you can hand feed them! The lake is beautiful, and if you like scenic drives, just driving in the hills around the lake is beautiful. Just a couple of ideas for you! Enjoy!
