The fuse box is under the driver side dash. The fuses for the RV are at the end of the bed. The truck chassis fuses are always dependent on the make and model of the truck, like 2014 Ford F-350. The mirrors are probably a function of the Body Control Module.

if it was me i would start with a new fuel filter and some STP gas treatment if you let it sit for a long time there maybe water in the gas tank and try these websites to see if they have your motorhome listed its www.autozone.com and the other one is www.alladtadiy.com if all fails stop by your local library and get your hands on a Haynes auto repair manual for your motor home
