Used to be, might still be around, a jon boat with a truck topper mounted on it. Made a nice looking cabin sort of thing. This year was my first year back on the water in several years so I don't know if it is still around. I never got a real close look at it but IIRC it was turned around backwards where the tailgate opening was in front. It was a local boat,I only saw it on the skunk a small river here in SE Iowa, which surprised me since I would think it would be most useful on bigger waters. Anyone use a topper sort of thing while fishing colder temps?
