Wow,I was just surfing the WTW site and came across this post.No they don't give me free sites,bummer.In Yellowstone when you camp at a reservable campground one of the first things they ask is the size of your rig,(they ask for feet) than assign you a site or you can request a site by number and if it's open you can get it.At Madison campground they do have tent only sites but a lot of their tent sites can fit our rigs.
No royalties on the flaps,though I might make a mod to mine by using threaded elbows instead of slip on.Just that they won't come apart so easily.But they sure work nicely and so simple.I try to design the mods I make to" KISS" like the rear awning I made from the cargo cover from my Ford Escape.I like the simple design and it only takes about to the count of 6 to set up and doesn't need any storage like the New FWC option,and less expensive.IMO.The rear awning is under the ATC thread "rear awning part dour",check it out,there isn't any charge.
I'll have to search the Xnaterra site for that campground picture,don.t know where they got it.
