I have had my F1 for about a month and I am very happy with it. I traded a Chevy Avalanche for my 2012 Ram. I did like how the cover worked on Avalanche except that with the high sides you had to climb into the bed to get the last partition out. You also had to store them somewhere if you were hauling something.
The F1 has been bone dry and it has been through the car wash several times! The Avalanche always had a little moisture get in but not bad. This cover is very light compared to the Avalanche cover and retracts in a minute. I purchased mine on the internet for $784.00 & free shipping...!
