    Having a problem with our Kenworth T660's, they all seem to get moisture in the fuse box from time to time. I assume we are not the only ones with this problem. Has anyone found a solution? Any help would be appreciated.

    There should be four or five grommets at the top of the firewall above the fuse box, check those. If they're iffy, just squirt some RTV in the grommets and put them back in. In my experience that is the #1 source for all water leaks in the firewall on KW B-Cabs.
