I want to see something like this brought to market.
I've done a few traverses in the PNW where the beginning and end are on dozens of kilometres of logging roads, while the rest of the trip is on glaciers or icefields. Half the time I want just a pack, but the other half a pulk would be better.
If the pack was built with the "rulk" in mind, there would be a couple of benefits - by having one side of the pack replaced by the aluminum of the rulk you would eliminate the possibility of snow running along that side, resulting in less drag and wetness.
Rather than using flexible tent poles to pull the rulk, what about a couple of rigid poles, that can then be used to support a pyramid shelter?
A "keel" could help with tracking, and a foldable outrigger could help with stability.
Jorgen, did you ever meet a young man named David Persson? Your stories of service in the Swedish military reminded me of him.
