This is for all you full timers: Got an email offer to buy a lifetime membership for $300. Now to clarify why I'm asking full timers. You guys probably spend most of your time doing monthly or longer stays in the campgrounds. I don't think you get a Good Sam's discount for that. So...is it worth it? Do you use something better? We are going to be work camping for the next year or two and then traveling more. There are lots of special RV programs out there. Opinions please.
