Started the aft seat floor. There are three hinges that get installed - the seat backs install on any of your choice. I want it far forward even though I'm 6'2" so as to increase the angle between the seatback and the seat cushion. (Edit Aug 3) - I added one hinge more forward than the plans called for - but after inspecting some RV's at Oshkosh and sitting in a couple, i can see that this won't work since due to lack of space with the stick. Basically, if I pull back the stick hard, I'll smash my nuts!!
