Retract Pro MX
I could not make my mind up on a BakFlip M4 or the Retrax Pro MX because of the difference in the price, you can almost buy two BakFlip M4 for the price of one Retrax Pro MX, but the reviews is what made my mind up, i owned a BakFlip on my last truck and it started showing wear within a year, the reviews on the Retrax Pro MX shows lasting longer and I hope I get a long time out of this product with it's warranty and reputation, and by the way it looks awesome on my truck.
I park on a steep Driveway, and so I was worried about rain leaking in from the Cab Area, but when I opened the Cover, it was still dry. It seems that there is less drag on my truck on the highway as well, especially in the Texas Wind. I like that it is removable when I need the whole Bed of the Truck. It is not to heavy but seems to be sturdy. I do worry about the locks sticking up on top of the cover so high that they could be pried off, thus the 4 stars instead of 5 stars.
