The RV dealerships tell me I need at least 4,000 running watts. However, I’ve read on many sites that all I need somewhere between 2500 to 3500 running watts. Any advice/suggestions?
I went down the path of a Westinghouse igen 4500(3700 running watts), it has a 3.4 gal tank will run upto 21 hours at low, or 18 hours at 25% load (this is 5.3 hours per gallon at 925 watts)- I typically get about 15 hours running my 15k btu a/c, residential refrigerator, 50” TV, etc. (about 1800 watts at max), it weighs 98lbs, fits under tanneu cover, has 30amp rv plug, wireless remote start/stop, wheels and telescoping handle, digital monitor that shows - fuel level, run time remaining at current load, current power draw.

$950 and has a 3 year warranty

Microwave, blow dryer, toaster, coffee maker, AC, etc are all high draw units. If you are careful to run one at a time your power needs are much lower.

I used a 2400 Yamaha to run our old RV. It has a std 13k AC and the genset did fine, as long as none of the other high draw stuff was running. I suspect a 2000W unit would run your 8k AC just fine.

You might want to consider a dual fuel inverter. I run a Champion 3400/3060 Watt unit. I normally run on propane, which gives me about 14-18 hours on a small (BBQ) bottle and I still can run on gasoline if needed. In addition, I don't have to worry about running the carb empty on shutdown and not having to clean it.


Also, if you use a gas model, run it on non-ethanol gas. Less worry about water in fuel, fuel separation, etc. It will also last much longer.

To figure your load you can just use volts x amps=power so if you have 30A service you have 120v x 30A = 3600W so that will be the max you should need.

X2

In addition to running on 90 octane non ethanol gas - I recommend treating your fuel with stabil to prevent any long term carb issues.

Please remember that not all folks out camping like the sound of a generator any time of the day. I would suggest that you do everything you can to minimize generator use. If you must use the generator buy the quietest one you can find and keep as far from your neighbors as possible. Myself I use solar. I can boondock just fine without using a generator.

Solar works for some... who don't have/use AC when camping in the heat, but Solar will not sustain an Air Conditioner.

I have in our 42 years of boondocking found that you will find someone nearby that will complain about anything you might have going on in our campsite. Some of the things we have had some grumpy old dude come over to complain about:
** Kids too noisy when playing catch (they are certainly louder than the generator).
** Dogs, on the leash.. Off the leash... peeing on the trees... barking at the grumpy old dude coming into our camp with a big stick in a threatening manner, even leaving their water bowl out overnight.
** Friends arriving at camp late at night (headlights of the car are disturbing their wildlife)
** Having a campfire, Tyler playing guitar (acoustic) at the campfire.
** and the worst of all - running our genny at 2PM-4PM to charge our batteries and cool down the insides (over 100F inside) when the grump was not even in camp.

Solar is not going to solve any of these either.... so, run the Genny when it is needed - the grump will come over and complain about something, no matter what.
