I had an A.R.E. cover on my Ram and I loved it but I just ordered a Bakflip cover for my Tundra because I want to try one that folds on itself. The fiberglass ones are a bit of a pain to remove. I am sure Bakflip will come out with a long bed version soon.
I really wanted the Snugtop. Unfortunately there doesn't seem to be a dealer network in the upper midwest (WI). I ended up pre-ordering an A.R.E.. They are supposed to be out in May. I hope so, because I am going to MT to visit family. Price was about the same for both caps.
