You've got those 'ladder' racks on the side. Cut porky in half and hang a half on each side, the lower the better as long as it's high enough to get down the trails without hitting rocks & stuff. Having the weight low makes a big difference when climbing. Also, getting it little more forward helps a lot on uphills. Whether you can do that depends on how the bike's designed. The more weight you can get in front of the rear axle the better.
A couple pieces of canvas are very useful this way to keep the meat clean.
