I carry a 25’ 30 amp cord. I use it all the time at home and have only on one occasion. Used it on the road. I also carry a 35’ 12 gauge 15 amp cord that I run from the power pedestal to my outdoor cooking area. Between the electric frying pan, coffee pot and ice maker it is nice to have the extra power available and not be just limited to the single exterior outlet on the rig (which happens to be on the same circuit as a bunch of indoor stuff) If we are ever in need of longer for the main 30 amp cord I can use this additional 15 amp cord and limit the amount of things we use. In our area power for the furnace is more important than AC anyway and a 15 amp circuit handles this easily.
