Has anyone bought or seen gator tails duck blind on the gator tail boats using the T-Rail gunnel? I'm wondering how it functions. It's priced at 850 which comes with all mounting hardware and grass. Is it worth it or is there DIY designs using the T-Rail gunnel system that's maybe alot cheaper? I feel if it it saves a decent amount of money to do it my self I don't mind. But to save 150- 200 but have to fight making something work........ Any thoughts is appreciated.
