First attempt, turned out good for me, helped quite a bit thru the snow, transiting bare ground getting to hard water and off again, and glides across ice - have to watch it when wind is at your back. I have a few changes to get too soon that deal with the cross bars & considering a few LED lights for the early AM.
It uses 4x bolts that drop in - allows it to assemble/disassemble in less than 2-4 mins
Recently chose to first insulate interior ceiling and wrap around area of the sides nearest the back of the trekker
Tend to leave phone on for wife, kid, work so needed to have power as it drains too quickly on the Western side of PP + will use it for LED lights
