Usually the cord is fully uncoiled, but this time the RV was close to the house so I left the cord coiled on a stepstool, next to the RV dogbone adapter. When we returned from a shopping trip we had a moderate sized campfire on the stepstool, 2 feet from the RV. I grabbed the fire extinguisher and put out the fire. The house breaker had tripped, but too late to prevent the cord heat from igniting the cord insulation. Amazingly the RV wall was warm but not damaged, and the fire had not spread. Could have been a disaster but we were lucky. Lessons: 1 - Use a 12/3 cord if you are powering a residential fridge plus charging house batteries; 2 - DO NOT leave an extension cord coiled in use; 3 - Fire extinguishers are worth their weight in gold. Know how to use yours and be sure it is ready for use.

I noticed that a 12 ga cord got warm when running my RV on a 20A outlet in my garage. Certainly itís adequate but I carry 50ft of 10ga cord now. Couldnít hurt...

In 2003 I had a home built in Pamlico County and lived in my 2690 Layton TT on site. Part of the electrical work was to install a temporary 30A outlet to power the TT. When electricity was wired into the house, I had the 30A outlet moved to the house.

Best $50.00 I ever spent. It has its own dedicated breaker.

Some time this summer or next I'm building a log cabin in Western North Carolina. You can bet that I'll be adding an exterior 30A outlet for my RV and the RV of guests.

You might also consider only 50 ft or less of 12/3. Sounds like the 100 ft is too long when at home. Do you by any chance know what the size of the breaker is in the electrical panel for the outlet you used?

Any 14-gauge cord between 0 and 50 feet long should adequately handle loads between 10 and 15 amps.

Those long runs can be trouble especially if not needed.

10/3 extension cord is the only safe way

Even then check plugs and adapters for heat

I have never have used an extension cord without creating heat when connected to the MH or previous campers
