My series 6 project came with the optional baggage sack but no assembly instructions. I assume that the honeycomb floor goes on the inside of the sack, correct? Although I'm currently not planning to extend the baggage compartment floor aft of the normal zone to handle a pair of snow skis or two. I might consider it if someone has a really great idea. At a minimum I would like to possibly add a plastic thin wall tube as a fishing rod holder near the top inside edge somewhere with access from the aft end of the sack. What sort of options have been created to add something like this and how have they been attached to the structure?
