Nice idea....I like it. The first thing to enter my mind when I saw the first prototype was that I preferred the larger wheels.
As far as the niche market thing goes, so what? I think it's a pretty good sized niche. There are a lot of older riders, myself included, who would like to combine their love of riding with camping...but need something more than a sleeping bag & pad between them and the ground. The ability to carry hunting or fishing gear is a serious plus for many of us also. I see Spud as a good way for many to get back to outdoor activities that they had given up.
Good idea and good luck with bringing it to market.
