It was the Horse Hide Hauler first in 1969, and then released later in 1969 as the Surf 'N Van. After that is has never been seen again.
Be great to see Round2 dust this one off, and re-issue it. Looks like it re-uses the Surf Woody's frame and engine, but without a side by side look at the parts, it is hard to tell. It would not surprise me if the chassis at least was re-used. That was a major tooling project on the Woody, and I can see trying to get all the mileage out of the tool that they can. Looking at the pics of the Built Kit, it looks no worse than many other Showrods of the day. I'd happy to buy it & build it.
Edit: Adding a link to a build thread of this kit at Showrods.com. Looks like the chassis IS the Surf Woody. That Gas Tank look familiar too.
