can anyone please give me a clue as to what it would take to connect a honda eg5000cl generator properly to my 50 amp coach. the generator has a 3 prong 30 amp locking recepticle and it has a 4 prong 120/240 volt recepticle. if i had to guess....i would say to get a 3 prong 30 amp male locking recepticle to 50 amp coach female recepticle but i cant seem to find one. my onboard onan is down for what i would expect to be a clogged fuel filter so i'm just try ing to find a good safe work around. i have a 30 amp/50 amp dogbone.
