i went with the tri- rough cover , very simple to on/off , the latches in the back ( by the tail gate) have adjustment screws so you can adjust for whatever the need , i can take completely off by myself in two minutes or less , it has been in a couple of (raines) showers at best nothing HARD yet , no issues with water coming in , i have been in several very dusty areas with no issues, it tri-folds flat at the back glass, i can sit on it , it says it can handle 400 lbs no problem and i beleive it, i paid $ 800. i considered the bakflip but it has more moving parts compared to this one , rails and all , it looks like a fine product and rides flush , but the one i got looks rideing approx, an inch up on the Raptor , IMO, i think most of them are really good and its just a matter of what your opinon is ! i am very satisfyed and would not change, for what ever its worth !
