Honestly I’m not sure how much the whole system weighs. All the plastic pieces are light of course. All the weight is in the rubber mat which has some heft to it. Perhaps DualLiner could tell you how much everything weighs for whatever length bed that you have.Do you know how much the whole system weights? I'm kind of leaning towards this options as it provides sidewall protection, cargo protection and I could do a sprayliner on the floor if I plan on doing "real" dirty work and don't want to damage the rubber liner.
