The lifetime warranty makes the price sting a little less.The reasons I bought the Retrax ProMX.
"The RetraxPRO MX not only provides rugged protection for your truck bed it also provides a patented low-profile design that enhances the appearance of your truck. The compact storage container features a unique spiral track system that prevents the cover from coming into contact with itself as it opens and closes. The operation of this cover allows it to always stay flush to the rails and creates a dependable seal to help keep the elements out and protect your cargo.
The RetraxPRO MX has a sealed ball-bearing roller system that glides effortlessly along the rail with a convenient handle that eliminates the need for pull straps, Velcro, snaps or springs. The RetraxPRO MX is key lockable in any position that gives you unlimited flexibility in your hauling capacity."
It's lived up to everything they claimed.
How much snow it’ll hold is my concern. Their description says it’ll hold 500# distributed, but it doesn’t say what size bed they base that on. For these short beds, that works out to ~2.3oz/sq” (substantially less for larger beds). That’s a pretty thin layer of snow.Oh, I haven't had the need to put a lot of weight on the Retrax cover. But, it seems substantial enough to handle a good amount.
