Inverter requires multi batteries, which I assume you have, and MW would be dead when boondocking without GEN=ON, so unless you are running GEN to run MW, you have Inverter. Inverter usually VERY CLOSE to batteries, (to limit long runs of BIG cable); I would be looking in compartments each side of batteries, maybe even mounting to compartment ceiling? Otherwise, just crawl under and FOLLOW each coach battery big cable= 1 to GEN, 1 to engine and 1 to Inverter, 1 to FUSE PANEL? All probably in corrugated protectors? Good Luck
