I leave the thwarts in and try to get my seat as far forward as is comfortable using the front thwart as a footbar. At 165lb sometimes the front end still feels a little light so I'll throw the daybag and other stuff up front to help even it out. A 5 gal jug would work, but i'm too lazy to bother. You're going to be moving around alot anyway, highsiding, ect in bigger features.... body "english" helps.
more snow = more water
