We will be adding a ton more information to the website to describe the BAKFlip F1 Cover.  However, you can purchase the BAKFlip F1 Model immediately knowing the following:

The cover looks very similar to the BAKFlip G2 (Generation 2) Model and it operates identically to the G2 Model.  The differences between the 2 covers are:

The BAKFlip F1^® (Heavy Duty) Tonneau Cover / Truck Bed Cover has all of the great good looks and functionality of the BAKFlip G2 (Generation 2) Model but in a Heavy Duty / OEM (Factory) Quality version as this cover's outer surfaces are Fiberglass Reinforced Plastic (FRP)!  However, the core of the BAKFlip F1 Tonneau Cover / Truck Bed Cover is 35% more dense, and is much more rigid then the G2.  The BAKFlip F1 opens, closes, and operates identically to the BAKFlip G2 Model, however the BAKFlip F1 has the following refinements: 

• The BAKFlip F1 has textured Fiberglass Reinforced Plastic (FRP) on the outer panels.  These panels are UV protected to prevent fading, warping, cracking.
• The BAKFlip F1 has tough textured aluminum surfaces on the underside panels.  These surfaces have a double coat of epoxy primer that is baked on at 460 degrees.  This process is done twice (2 coats of primer) before the final coating is applied.  Once the two coats of primer has set, an extraordinarily tough and scratch-resistant polyester based coating is used as the final finishing coat (which gives the look of a tough, baked on enamel, but is much higher quality).  This coating process ensures that the covers is both scratch and UV resistant.
• The BAKFlip F1's core is 35% more dense than the BAKFlip G2.  As a result, the BAKFlip F1 handles approximately 35% more distributed weight when compared to the G2.  The F1 is more rigid then the G2. 
• Quality and Rigidity Standards Endorsed by OEM - The BAKFlip F1^® is an Original Equipment Part for one of the Big 3 Automakers
• 2 year warranty for the BAKFlip F1 vs. 1 year warranty for the BAKFlip G2.
• Powder coated pivoting arms are provided on the F1  -  (G2 has zinc plated)
• Integrated tie down points underneath and on top of the cover (“D” Rings placed at strategic points under the cover).
• For an extra $250...you get the absolute best product for your truck with the BAKFlip F1
