The roller that contains the Retrax cover takes up 13.25" at the front of the bed. I have a short bed. 2 dirt bikes wouldn't be a problem. Two quads might be depending on how you were going to carry them and long or short bed. I got mine from Max Power here on this site. Great guy to deal with.For those of you that have a retrax, I was wondering how much bed space do you lose and also can you still carry 2 dirt bikes or quads without removing cover.
Also if anyone has a place to order from I would appreciate the recommendation.
