I looked hard at the Pro V GL this winter and had a couple of dealers tell me they weren’t ordering any new Lund glass boats in 2019 due to uncertainty about the new production line. That was one of the reasons I went down a different path.
I know Nelson’s Marine got 4 of them this spring and they didn’t speak of any delays but they had been ordered in mid-2018. Given the dealer concerns it doesn’t surprise me you are having some issues. I wish I had more info to share and hope you get your boat soon.
