Hi drwalker,
I was hoping another Torque owners would see this post and provide the exact location of the fuse box. Since they haven't yet, let me guess. The fuse boxes are typically at floor level, often inside a cabinet and behind a plastic cover. With floorplans that have batteries on the side, the fuse box is usually located within a few feet.
If you still can't find it and no one chimes in with the exact location, call Heartland Customer Service at 877-262-8032 / 574-262-8030. Have your VIN # ready. They can tell you.
