Since your rig is light, doesn't have a lot of power, and only has 35" steet tires I would think the front end would be OK with some weight added to it. Kurt is probably running a 4.0L? If so then it probably does have quite a bit of front weight. If your rig weighed 2700lbs (just guessing) and was 50/50, adding 200lbs would get you to about 53%. That might be too much weight to start out with, but try filling them up halway and take it to Hannibal to practice some time. The ideal way to do it would be to practice with and without water in the same day. Traction and terrain changes so much on the east coast that climbs that you did last year may be better or worse than last year.
