If you have the same motorhome as mine, Seabreeze 1341, there are 2 chassis fuse panels, one in top of the dash board directly over the speedometer. The access panel is held in place by velcro just pry it up carefully. The other fuse panel is in the engine compartment, just open the front engine access (where you check oil and trans fluid, etc..) and you will see a black box right in the middle, if I recall correctly mostly relays in there. Coach body fuses in mine are all in a compartment under the closet in the bedroom, but that is not where the one for the brake lights will be.
