I am getting close to wiring my coach. I will have a propane stove and oven,hse refer, 110/propane/engine heat exchanger, water heater, webasto & propane heat, Inverter with 10 deep cycle batterys, 15kw gen set, and normal other stuff. Do I really need 50amp or will 30 amp be sufficent?

Thanks Nelson Thomas

Wire the coach for 50A ,
two seperate legs of 120, so you can run a hot water heater or 2 air cond at the fancy (& rare 240V/50A)campsites.

When in a normal campground the 30A power hose can use a cheap adapter to power both 120V legs from 30A provided, and is far lighter to coil .

Attempt at all costs to set up the coach for 15A/ 120v as Normal.

Now you can visit friends , or choose the finer older campsites , where the location is fab , but the power is antiquated.

Works for me, 15A is great living if no air cond is needed.

I'd go with 50amps. Won't cost you a great deal more at this stage of conversion. Besides having the capability to run two ACs, in the event you add more electrical stuff later, you will have the power to run it. Also will make your rig more desireable in the event of a sale.
80% of the campgrounds we've parked have 50A available.
Wondering why the 15KW genset, though. The 7KW in our all electric bus, except for diesel heat, is very adequate.

Hardly any more work to do 50A from the get go. It is easy to dogbone down to 30A when in parks with only 30. Quick answer: 50A.

50 amp for exactly the reasons Fred said. Don't install any 240 volt stuff though. That would screw everything up.

8KW or so should be more than enough power (66amps of 120V) 15KW is 125 amps and the unit will be underloaded. It will soon learn to use lots of oil, smoke & stink. It will be about twice as heavy for no reason.

We have a bus with two roof airs & electric water heater, equipped like yours & we have to add a 1500 watt space heater to get our 6.5KW fully loaded for testing.

We have 50amp in our "georgie-boy" and ran both airs, the
microwave, TV and the wife's hair dryer while connected to a
campsite's meager 30 amp service. Go with the 50amp, you can
still connect to 30amp or even 15, when needed. It's tough to
move up later.

From Nelson
I'm useing the 15kw Onan because I got a never used 1977 model for $100. It was designed to run from the power take off of a tractor. I will be running it from a 4 cyl. Thermo-King motor. I expect to have a relly nice diesel Generator for less than a thousand Dollars. I got some good advice from a gentelman in Florida on how to set it up. I agree 15kw is over kill but the price is right. It also is enough to power up my all electric house in a ice storm. Thanks for the advice on the 30/50. I will go with the majority of advice and do the 50amp

I am building for a 50 amp 120 VAC (you read it right) using the SW4024 in the line as a peaking power supply source and consumption regulator. That way, you could keep your power consumption down and run even a lighter overall load while keeping things like one AC in service. I will be able to visit and plug into a 120VAC outlet at 15 amp and still run the coffee pot and the AC at once (although not a long time).

The SW 4024 is a very smart box that can give you a great deal of freedom and flexability of used properly. My 50 amp hookup is actually half of a 240 line for the "delux" locations. My gen set on the road and the coach alternator make up the difference on the road.

For travel, I have a 6500 watt HOonda gen set (RV style) to supply the 120V

My way
