The adapter Frederick suggested can be used but SHOULD
only be used to power down to 30 amp. Not to power up to 50 amps.
Please, Please do not use the adapter to make your rig a 50 amp! The wiring in your Bigfoot
is 30 amp wiring. Meant to have only 30 amps of power running thru it. Now does his suggestion work, yes it does. But I have seen what can happen when someone thinks that just because they can plug into 50 amp means they can use up 50 amp........
I swear I wish I had a picture of the trailer cord, as well as the adapter Fried
. Thank God the one persons converter stopped it at that point. It burned everything from the converter out................................ Another one I saw the end results actually fried some of the trailer wiring.
Again, it can be used. I carry one. For the main reason of pulling into a Rv Park and the only site they had left was a 50amp. But I understand amperage so I know not to get everything going at once, just cause nothings tripped.
If you read the manufacture recommendation on the package it recommends it be used with a 50amp rig to power down to a 30 amp pedestal.
As for your "lot" you can have a pedestal put in that has both 50 and 30 amp at it. Just like many campgrounds/rvparks. The 50 amp is there for future use if you were ever to decide to put a 50 amp rig in place as well as a great selling feature should you decide to sell your "lot"
