If you are not familiar, I wasn't until I joined JOF, you can make it easier on you gen set to start your air conditioner if you install a Hard Start Capacitor Kit on your A/C compressor. This capacitor provides a little extra voltage boost when the A/C first starts up and hopefully you can avoid an overload situation on your generator. Many in this forum also speak to using a start up method by starting first with turning on the fan, waiting a bit and then starting the A/C so as to spread out the amp draw and make it easier to avoid the overload.
This is a very inexpensive mod and requires only a screw driver to install. Why Jayco doesn't just have these installed as standard equipment is beyond me. The kit with shipping was $25 and the install time was about 20 minutes.
I know many have posted about installing A/C Hard Start Kits. I first contacted Coleman (Airxcel RV Products) and they warned me not to use the Supco kit as it sends too much voltage to the compressor and long term use will cause damage and shorten the life of your A/C unit. See link for part #, pictures and easy step by step instructions.
