Well in full disclosure. I helped invent them and am one of the founders of the company. Soooo, out of respect for the Rokslide I'll do my best to answer real questions honestly, without being too sales driven. I'll start by saying that I live in Montana and am an avid hunter, as is my 17 year old daughter. We designed this after years of frustration with Fiberglass toppers. Once they are on, they are a pain in the ass to take off and store. We also have made them completely tool free, so you dont have to even mount anything to your bed rails. They are simply cam strapped to the tie-down points in the truck. Id say they are designed for the person that doesn't always want a topper on their truck, gives the flexibility to take it off in minutes and light enough to deal with on your own. Also due to the rigid construction you can haul a load on the roof, sit on the roof to glass and made of the same rigid drop stitch as SUP's and Raft floors, so quite durable against daily driving and off roading.
