Generator size

I'm looking at an American Coach Revolution 42W. Just wondering about the 8 kw generator with three a/c units and an all electric coach. Is it big enough to run the coach if we are off the grid? It looks like it might be a toss up between this and an Entegra Aspire. Thanks!

AC is a first class operation, if they put an 8 KW in there, it's probably okay. However, if you have doubts, call them, the techs are very sharp and very helpful.

I assume you have six 6V coach batteries and possibly two inverters. Your generator should be used primarily to charge your batteries.

Do you plan to do a lot of boon-docking?

If not the 8K is more than enough.

If you are planning to run 3 AC units, microwave, fridge, 3 tv's, charger, and all your lights and water heater (Aqua hot), pumps all at the same time for an extended period of time, you would
probably consider more, though an 8,000 watt generator should be more than enough. BTW the Revolution 42W is quite a beautiful Coach. I would be more concerned about the engine using DEP.

If it is, you might want to see if you can get a grandfathered engine.

I absolutely love my 2005 Revolution, but the floor plan in the new ones is outstanding.

Best wishes, I am sure you will love either one. I myself would go with the Revolution.

Our 6.5kw is BARELY good enough to handle 2 air conditioners plus electrics, and ours is not an all electric coach. 8kw might be enough for 3 air conditioners.

If it's a concern, I wouldn't consider buying until you've had opportunity to test it and put it through its paces. Make sure it really can do the job before you sign the dotted line.

You actually would have two "legs' of 4000 watts each. ONeof those legs has to support two a/c's, while the other has only one. But your electric cooktop, microwave, fridge, water heater (unless it has Aqua Hot), etc. all have to be somewhere too, plus anything you plug in, e.g. coffee pot, hair dryer or whatever. So yes, you could easily run out of power if you try to do everything at once, or the wrong combination of things.

The American Tradtion and American Eagle models come with a 10k generator for just that reason, but the Revolution is a less expensive coach and therefore has a bit less of things. You might be able to get AC to upgrade the 8k to a 10k (for a price, of course), but you may find other things that are less than what they could be as well. If you don't want to come up short anywhere, consider getting a Tradition or Eagle instead of the Revolution.
