I am in San Antonio TX and I will be heading towards the FL Keys. I am pulling a 32 ft travel trailer with a GMC 2500 diesel. I would like to take the straightest line possible from San Antonio TX. When I say desolate, I mean a place where there are no RV's next to me. For example, my favorite spot in the country is in Green Ridge State Forest in Md. It is 10.00 per day and it is dry camping. When you are outside your RV, you see nothing but trees and woods. Each camp site is secluded and far from each other. Something like BLM Land maybe but there is no BLM land on this trip. I can dry camp or run off power. I am willing to get off the interstate. I also am a member of Passport America and Escapees if that helps. TX, Louisiana, Alabama are all fine. However, I rather not be by alligators. They scare the heck outa me.
