Thanks chaps & hello Wengen007, yes the standard Cal-Topper is about a 3rd bigger and doens't go in the tailgate with the chairs. Also the material is heavier and takes a little longer to dry out than the compact version - which pretty much shakes dry. We plan to phase the heavier weight one out this year as to be honest we only sell 1 to every 20 compact versions now.
Hope this helps,
Andy we still have some business to sort out on the 5th seat you'll have to drop me an email when you get a moment
Thanks Nick
