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?
The Yamaha EF3000iseb "boost" technology sounds good on paper. However, who knows in the realworld.
If your primary use is just powering a 1500w (12.5a) heater, a 90w (.8a) CPAP, and the converter (worst case 7-9a), a paralleled pair of Honda EU2000iS and the Honda EU3000iS will probably work just fine. The Honda EU3000iS has the added bonus of being the most quiet generator of the bunch--by far. The paralleled Honda EU2000iS's have the added bonus of being much more portable and slightly more powerful than the EU3000iS. It's much easier to carry two 55 lb. EU2000iS's (wet), then one 155-160 lb. Honda EU3000iS (wet).
If runtime is a concern, there are a number of after-market, external gas tanks available for both Hondas that will allow operation for over 24 hours without refueling.
If saving $1000-1100 interests you, you may want to consider the Champion 2800/3000w 75531i (an inverter generator just like the Hondas). It weighs about 95 lbs. (wet), capable of more inrush current than the above-mentioned Hondas, not to mention Champion's reputation for excellent warranty support. Downside is the sound level. The 75531i is a tad louder than a pair of paralleled EU2000iS's, and quite a bit louder than the super-quiet EU3000iS.
