Below is a picture of what I have right now. Bench at the back, offset console in front and a coolbox which I could happily lose.
I take my two children out on it (5/6). They love it but tube seating is out of the question for them. It's the bench seat or nothing! I'm left standing on the left. It's doable but a bit awkward to reach across to the throttle.
Ideally I'd like to move the console to where the coolbox is and have a single jockey behind it for me. That would also give the kids an extra grab handle at the back. Do you think it would all fit? Is it a big job? I would need to run new engine and steering controls, as well as extend the gauge wiring.
I haven't even investigated how everything is fixed to the deck. Must be pretty substantial I'd think?
