So would I be better to use 2-2000w generators or a single 3000w. The 3000w seem to have a larger tank but maybe not once you add the 2 together. The other one I looked at was the yamaha 3000iseb which clais 3500 starting watts. I have found quite a few leftover 2013 units and it looks as though I can buy the 3000 watt ones for about same price as 2-2000 watt generators and pairing cables. Don't know which to use.
Keep in mind I may never use these for the RV but would like to run my enclosed trailer and household essentials in case of outage. Primary use is enclosed trailer running 1500w heater CPAP 90w, phone charger,GoPro charger, battery charger for GPS, and charge the deep cycle battery for the trailer interior lights.
Also can these generators be used for 120v output and 12v charging at the same time?
