Question:
Hello. What would you recommend to hook my 240V 30A inverter generator into the smart plug 50 inlet? Just bought a used 2019 ATC 2419 trailer and will be changing out the current 50 inlet to the smartplug. I want a good way to use my generator when needed. Thanks.

Hey Pat, congrats on your new trailer. Since you're converting over to a 50 Amp SmartPlug RV Power Inlet like item # SM56FR, you can use the SmartPlug Marine Power Cord Adapter - 50 Amp Female to 30 Amp Male Twist Lock Connector item # SM43VR
This 4' adapter lets you connect your 50-amp SmartPlug cord to a 30-amp twist lock. It is only rated to 125 volts though.
We also have the SmartPlug RV Power Cord - 50 Amp - 30' item # SM86FR and the Angled RV Power Cord - 50 Amp - 30' item # SM54SB. You would also need to use the Mighty Cord RV Power Cord Generator Adapter item # A10-G30350VP to connect to a generator with one of these 50 amp cords.
Do you have any fun trips planned yet to break in the new camper?

Actually I haven’t done anything yet with the generator. Had to get the main power fixed first and it’s done now. First trip is hopefully on march to Arkansas and Texas.
