Does anyone run the 8ga Lance plug?

Just curious if anyone here runs it? Is it worth the asspain? Do I need a beefed up alternator to keep up? I usually just run the fridge on LP without any issues as it murders the batteries with a quickness in DC. My camper came with an extended cord to plug in at the hitch so it plugs in at a y down there with the trailer. Were I to add a connection inside the box, I'd prefer something gooseneck compatible.
