When I bought the TR-18 the one grip I had was the deck. Behind the butt seat, there was barely enough room for a second person, and a couple people have fallen off of it.

Dropped the boat at my friends house, and he built me an extension and new step that turned out better then I could have imagined. Gained 17" of deck, and the step. Needless to say, it's like a different boat now. This will make it easy for 2 people to fish up front without falling over, down, or in the water.
