For the type of riding I do, backcountry, this would work well. If we, Team AARP, ride more than 6 hours, that's pushing it. We don't cover a lot of miles, usually. Like others have said, the infrastructure would have to be there first.
Not a sled, but, 3 years ago I bought a Karavan 6x12 utility trailer to haul the sxs for 1400 bucks from Fleet Farm, that same exact trailer today is 3k!
