WE have a 2018 Relfection 337, we have one AC unit, just getting ready to install the Magnum 2000 Watt inverter. We are shopping for a generator and want a size that is somewhat portable but yet big enough to run our AC, and microwave, not necessarily at the same time. We want for sure an electric start and probably a remote start. The unit i have my eye on is the Onan Cummins P4500i. 4500 starting watts and 3700 running watts. Should this unit run the AC and other small outlets at the same time?? Suggestions?
