I'd really like to be able to run the AC on my rig when I've got it parked outside the house before we take off on a trip. The 110V house supply isn't enough but I do have a 220V / 30A outlet in the garage which is a 14-30 outlet. I'm looking and reading but I don't see anywhere where I can get a 14-30 to TT-30 converter. 14-50 to TT-30 yes. Is this even possible (assuming that the 14-50 converter just splits 220/50 into 2 x 110/25) or am I looking at wiring in a new circuit?

Put in a new 10 gauge 30 amp 120 circuit.

I assume the OP needs a straight blade 14-30P.I would get a 30-TT pigtail and wire it to a Hubble 14-30 plug.One hot of the plug will not be connected.For a longer cord get a 30 amp RV extension and cut the male connector off.

I did 30 amp at my house. Home Depot had the RV 30amp plug receptacle and I used 10 gauge wire, as I recall.

I would get a replacement RV MALE 50 amp end and install the standard 30 amp shore cord extension. Cut the MALE end off the 30 amp extension cord. Install the 30 amp 3 wires to the 50 amp replacement head. Hot to one of the L1 or L2 of the replacement 50 amp end and then install the neutral and ground on the correct pins on that 50 amp replacement head. He now has a correct adapted plug and extra 30 amp cord to plug into his RV. Doug
