Iput one on my rig and a month later added the second one in my opinion two is the way to go. i also installed them myself took about 2 hrs for first one and half that for the second one i have a slidemaster and it mounts to the sides of it. also i never have to lower them to put in garage i have 2 8 footers
Blade is the one I'm waiting for I was told they would be for sale at the first of the month but now I am told it will be the end of the month till they will be shipped.
