This is a solid cover that is targeted at land surveyors, which I happen to be one. Our office never had one but we have another office that did. Its kind of nice since you can lift one side or both sides and have it come straight up about 2 or 3 feet like you want. You probably don't want one of these and as I recall, they are very pricey, but this might give you some ideas on how to make one. Its nice since you don't have to lift all four corners at the same time but can lift one side then the other or just lift the back like a regular hard cover.
