I read the review of the Avalanche in the American Rifleman and they purchased a tool bag to a small tool kit and put it in the side compartments. That got me thinking....the other night I was at Home Depot and saw they sell this combo bag kit (2 bags) for $19 so I picked it up. They even match my black beast. I haven't loaded them up yet, but was wondering what everyone else is using for portable storage in their side compartments?
