Air conditioning and generator

I have a 2016 Lance model 1985 with a Coleman air conditioner. I am wondering what the btu’s are?


I have a champion generator. It puts out 3500 watts running 4000 start up. How big of an air conditioner will it power?

    I upgraded the AC on my Minnie Winnie to a 15k btu one and I have run my roof air, fridge and microwave all at the same time with no issue. I have a 3000 Watt Onan genset.


    Agreed. As long as your not running multiple items at the same time that are high amp draws (Microwave, coffee pot, hair dryer or curling iron, toaster) and the AC, you'll be fine. If you need to run multiples, kick the AC off for a few minutes while your thawing the chili in the micro and your lady/daughter are using the hair dryer and then kick back on when their done.

    I use a percolator for coffee on the gas stove and cook outside generally so we seldom trip a breaker. Occasionally if she is using an electric skillet and powers up the microwave and then starts making the toast, we'll kick a breaker. She's bad at math and doesn't seem to remember, 2 items max from the above list all the time ;-)
