Hyrum...or bust!

[DanzTuna]

For my modification, I used table top lift mechanisms from Amazon and a pair of old skis from DI.  Was easy to construct and collapses nicely for storage.  I had about 100#'s of gear in the sled for my Hyrum trek and pulling was a breeze.  When the mechanisms are extended, the arms rest against a stop to prevent collapse with a load or when pulling.  You collapse the sled by stepping on the ski tips and pulling the sled forward. To raise the sled, you step on the rear tips of the skis and pull the sled backward.  I found several videos on YouTube of similar setups.  If you want additional details, feel free to PM me and I'll be happy to provide more info.
