Agreed.. I typically jettison my can once we start pounding a hill. Only planning on keeping some light weight essentials in the tunnel pack. Thanks
Too much weight on the back end is not going to help you sled float as good. If you do have a bag learn to eat what's in it by noon and pack just the essentials and as for the gas rack in the back same thing either drop it off or pour it in the sled.
You wouldn't believe how much 20-25 lbs off the back of the sled does in deep powder. Better weight distribution if you have a pack-sac.
I have an Polaris under seat bag, a Choko clutch cover bag and then my fuel rack and fuel can. Using the two rear seat bolts the Choko bag fits in between leaving 2" between the seat and the fuel can.
