Completely agree with you. On my F-250, I run a RetraxPRO MX but on the 5.5' beds, I prefer the MX4 for the same reasons. If you regularly haul larger or taller objects and don't want to lose the visibility, the Bak Revolver X4s and Truxedo Sentry CT are both great options.On the last 6 trucks I've owned (5 F250 diesels and 1 F150), I've installed Retrax Pro/Pro MX - as I believe they are the best money can buy. That said, I'm thinking about a BackFlip MX4 this time to avoid having the "can" at the front of this fairly small truck bed. Anybody have experience with this product or have another you think is better? Thanks.
