Given all the "storage" these sleds have, I don't get the wasted space at the back of the seat. My old Evinrude/Johnson golden ghost has a seat that flips up and you can put loads of stuff in there.
Someday these sled makers will figure out that MORE sleds are sold and used in the midwest and East, than all over the west coast and mountain areas, and will stop catering to the dufflebag on the back crowd, and put some dog-gone storage space on the machine. It is like an after thought at best and mostly a zero thought process. Doesn't function EVER enter into the design phase anymore???
