The fridge draws very little, just pick up a common & inexpensive #14 or #16 extension cord. At whatever length, up to 100'. The #10 - 30 ampere cord will work too with a 15 or 20 amp adapter at the outlet, plus someday you may need a 30 amp extension when camping and it's too far to the pedestal. I like my idea so much I'm headed to Walmart to pick up a 30 amp extension today! Will leave my #14 extension in the garage and pick up a 30 to 20 amp adapter as suggested above.
