Well update to all and to a thanks for the info.
Camping world is correct but also may have confused things.
L1 and L2 needs a jumper if using 30 amp generator. They most like meant Leg one and Leg two. Anyhow so be it. I hooked up all on the bench at home and did a test with two separate receptacles to simulate two 110 vols circuits. All works fine. So as not to worry myself to death over burning something up, I paid an hour labor to have the unit connected into the coach. i did all the preliminary and finish work. Works great! just due to the larger a/c, i need to turn on the fan first, then kick on the compressor. So having said all that I am up and running and have my cake and able to eat it too! The factory rep walked me through the workings of the switch in which taught me a lot. Well end of story, hooked up and I guess energized!!! Good Luck & Be Safe ! ! !
