rv extension cord

My three cents. In all the years of traveling here and there, we have only needed an extra few feet i would say less than half dozen times. We have a 50 amp, with only one a/c, I have a 30 amp shore power cord that I use when traveling, also have one 25 foot 30 amp extension cord, plus one 25 foot heavy 12 gauge cord that I have only needed a couple times, that was to help with someone else needing power when dry camping. I would get one 30 amp extension cord or a heavy 25 foot regular extension cord to use for battery, lights, and misc. stuff. you can run fridge and water heater on gas to keep load to a minimum. While traveling, but may not handle a/c. If storage can be an issue, the smaller of the two should work. OR, you can always wait until you need it, run on battery for the night if you have to, that's why we have fully self contained units. Good Luck & Be Safe ! ! !
