If you plug it into a normal 15A or 20A 110V outlet using an adaptor - which you can get at WalMart - make sure it's only to run the lights and a few other items. Do not use the adaptor setup to run the AC - it cannot handle it and may damage the AC.
A new power outlet for the RV can be bought at Home Depot and wired in for a nominal fee by a certified electrician.
Congrats and welcome to the Air Forums.
