Must've missed your orig post.
I have the Bronco and have made a few mods to it. First off for the single hander I put a section of lightwall PVC cut to accomodate the reel seat as a rod holder, just tie-wrapped it to the frame and it worked like a charm. The two-handers were a little more work to control.
Also put a lanyard with stainless clips on the front d-rings so I could stand up, fish and step downriver with the lanyard resting on my legs.
The platform behind my seat accomodates a 40-something quart cooler, but most often I would just use a roll-top sealine bag and a small padded cooler inside for lunch.
The unit comes with saddle bags on either side of the seat so there was no need to get carried away with additional storage systems.
One thing I always felt I should've had was an extra oar.
