I glanced at face book market place today. Someone has a generator split 20 amp adapter cord for $5. I check it out online, $30. We made arrangements to meet 2 miles from my house. Back home I look online for 30 and 50 amp rv plugs, $13. Do I want to rebuild the cord for two 15 amp plugs or two 20/25 amp plugs? Either way I've saved about half on a new cord. All campgrounds we use have 50/30/15 amp outlets in the box. My camper is 30 amp and I have a 50/30 amp adapter.
