I recently learned a lesson about Walmart. Some of the newer (it seems) Walmarts have installed gates to keep the truckers out. They are about 10' tall and usually painted yellow. They allow cars and SUVs to enter but are obviously designed to keep anything taller out. (They may just be enforcing local ordinances but can mess you up if you are counting on staying there).

I have started using Google street view to see what the ingress / egress path looks like. I really like knowing where I am going before I get there!

I agree with Tom and Chester. Truck stops are too noisy, smelly, and dangerous for me. Cracker Barrels have been good in my experience. (I always ask to speak to manager and promise to eat dinner and breakfast if they let me stay overnight). They always have. Be warned though that not all CBs have truck / RV parking.
