I will be eventually, getting a gen... anyone know,what the absolute most amps/wattage a jayco 29 G2 would draw, in total usage requirements,...= all 110 appliances on?
What are others using as a generator,and ones to stay away from....
i was just at crestview in austin and the few gen they had on display were outragous prices...

We run a 5500w with 8500 surge, does pretty good unless the hot water heater is set on electric and the microwave is going and the A/C then it trips the breaker sometimes ( very rare occasion ) Just make sure the hot water is on gas and helps alot! JMO

The maximum possible current draw will depend on the size of your service. Best I can tell, that is 30A. A 4000 watt gasoline run generator (3600 watt if running on propane) will provide all a 30A service can use. A larger generator might use less fuel since it won't have to run flat out at all times and might last longer since it won't be working as hard but but that is iffy and it will be a lot heavier to lug around.

On the odd chance your service is 50A, it would take 12,000 watts to provide all the juice a 50A service could use. Needless to say, a generator that big would be a monster. Good luck lugging that boat anchor around.

If you run everything electrical at once, you would probably trip the 30 amp breaker, even on shore power. I use a Honda EU2000, and as long as I'm smart, it runs everything except the AC. But not all at the same time. I make sure that the water heater is set to gas only. While the fridge doesn't take much electricity, I run gas only while on the genny.
I can't lift a bigger generator anyway, and it's always been plenty.

There are many things to consider when buying a generator besides the output. Sound is huge consideration when camping. Many of your cheaper generators (often called utility generators) will be very noisy. You also have to consider if you want a standard or inverter generator (inverter costs more, but will have much cleaner power for electronics). When I use a generator, I use the fridge and water heater on propane - much more efficient.

Your limitation, unless you upgrade, will be your 30A service. No matter how large a generator you get, 30A will be the most you will be able to use unless you upgrade your panel to 50A. Running an AC, microwave, and coffee maker at the same time on a 30A service is going to be iffy at best. Just the AC and microwave together will be pushing it unless you have a 15,000 BTU AC, in which case you probably won't be able to run it while the microwave is running.

Also, if you do upgrade and get a big enough generator, the bigger generator will burn fuel like the QE2. The generator will also weigh almost as much as the QE2.

jwb023-- To lessen you elect load you could always use an non electric coffee pot and use the gas stove or grill. The will take 12-1500 watts out of the load. You should be able to control all your loads and get a one of those Honda 2000, which are very quiet.ps you panel has "2 hot legs" which will provide 30a each take it from there. Larry

Dead on - my rule of thumb on 30A is two major things. And majors include AC, hot water heater, microwave, toaster, coffee maker, hair dryer. Obviously you can time things out, make the coffee early turn off and then the toast just before breakfast etc. Hot water & refrig on propane .....
