than the CG Ultimate. The full size american trucks have a bed depth of 19" that will fit even the DP Ultimate. If your bed depth is less than that it's a tight squeeze.

In my Tundra (16" typical Japanese depth bed) with the flush mount tonneau cover I had to remove the landing gear and then the tail wheel had a little pressure from the top.

Bottom line:
If your bed depth is less than 19" get the CG Ultimate (or do like I did and get rid of the truck for an SUV ).

If you bed depth is 19" and your pocket is equally deep, get the DP Ultimate (and a big motor!).

HTH,
