Best of luck in your search. We were seeking a used Super C (most LOA to long), so went with new 2014 Minnie Winnie (wife’s choice). Towing our Jeep we get 9-12 mpg based on wind and speed. It’s rated 30amp (which means 25amp continuous) and no problem with TV-1amp, fridge-3amp, water heater-4amp, AC-16amp all running.
We turn off AC-16amp to run Microwave-12amp.
IMO, know your ‘amp draw’ for everything in your RV.
We keep amp info on a 3x5 card for reference.
We NTE 25amp on our 30amp converter.
Easy to figure: Amps = watts divided by volts (120v). Watts = amps X volts (120v).
