We were parked in a friends back yard a few years ago and ran 50 feet of 30 amp RV cord and 2 25' 12 gauge extension cords. We ran the air with no problem and had 116 volts inside the MH. Guess you can get away with anything. Never did figure out what house circuit we were on but never blew a fuse.
We have a FR Stealth with the built in Onan and solar kit. I plan to sell my Yamaha 2400is generator and get the 1000w smaller and lighter model for times when I want to charge batteries or use outlets and don't want to fire up the noisy Onan.
I would like to get the 1000w generator about 75 to 100' away from the camper so we don't hear it at all. Can I run a 50' or 75' 120v heavy duty extension cord from the generator to the 30a RV cord (using an adapter) without resistance and heat issues?
I would buy one of these and skip the RV cord but I cannot find one that converts to a 120v plug.
