I have a standard height Econoline and would love to be able to stand up occasionally. The cost of a new high-top is more than I paid for the van! I see articles recommending scrounging tops from wrecking yards. Maybe when I was younger, but right now that is not very high on my list of things I want to do. I have considered a DIY option using a hard truck bed cover, canvas, and hydraulic struts. But, I can help but believe some enterprising individual wouldn't see this as an opportunity and fill the gap between the too expensive and the totally DIY project.
