I am wanting to try to run our coach using a 30 amp plug I have in my barn. It is about 100’ way from where I can park. Would I be able to make an 80’ extension using 50 amp cord with an adapter to 30 amp in the barn and the other end plugged into the 50 amp cord coming out of the coach?

From reading on the forum sounds like I will be able to run one of the AC zones on low with this setup.

Any experience with this?
