Im curious what you got sled and shanty?
I got jet sled jr, with little custom. i use rubbermaid tool box, and front add wood to level for 5 gal bucket bait.
here a picture of it, just give you some idea, if you not want to build the box, just buy one rubbermaid tool box from wal mart, and put on jet sled jr, it fit pefect!.
It my first own of portable pop-up hub style. I like it. It not that bad. I got it from ebay Killzone fit 4 people 6x6, last spring.
