I had a custom both sides finished hardtop installed 3 years ago. The top was made at a marine fibrglass shop and the supporting Aluminum pipework was done at my marina's yard. It looks perfect but it cost me about $20k without all the antennas, solar panels, low profile camper style AC/heat pump and electric wiring installed which I did. Then I had to have a new eisenglass enclosure made. Was it worth it absolutely in my opinion.
