Thinking a head here. And starting from scratch. Anyone seen a really neat wall switch. I don't want the light switches on the over head light's. Two reasons. 1 I just don't want the switch up there. 2 I want to make it simpler for Linda. Then thinking of having all 110 volt wall plugs in light almond. Then put all 110 volt invert er operated plugs in gray. Or any color that was different then almond. Could make all wall plug boxes in three gang. 2 110 volt, and one invert er. Or 4 gang with 2 of each. Bob Dunahugh

Since your scratch-starting, as you say, I would use switching relays to change power sources.
The default would be inverter, second would be gen, then shore.
That would save a lot of PITA running wires. Power would always be available in the wall recepticles.
Look at the newer 120v receps that also have the USB charge port built in.
Thinking ahead is a good idea, it can also prolonge the work schedule. Make a list and check it twice.
Just my few cents.

Hi Bob, sorry about your coach.
I put a DPDT 110V relay in my breaker box with the coil connected to the 110V coming from my inverter. I wired one of the 110v house circuits through the relay such that when I turn the inverter on the outlets on that circuit are switched to the inverter. Turn the inverter off and they revert to normal.

The relays consume the most power on the key fob device. I can see the relay is a SRA-12VDC-CL. Looking up that DataSheet shows the relay coil takes 66.7mA, so at maximum with 4 relays ON 66.7 X 4 = 267mA. The balance of the circuitry would take less than 50mA for a total load of under 325mA. Considering the duty-cycle, I would think it would total to less than 1Amp/hr per day.
On the other hand, using transistor or power FET drivers would eliminate the relay coil currents and greatly increase efficiencies. On the other hand, relays are very forgiving to mis-wiring , static discharges and surges, transistors and FETs are not. So for guys like Rob Mueller, I recommend the relay style.

my coach has simple rocker switches on the walls to control all the over head lights. They are all 12v and still have their switches, so you can turn them all on or off witht he wall switch and enable them individually with the fixtures switch.
Pretty simple and easy

I would put a panel of switches by the door, and do the two switch thing to another location if necessary for the 12 volt stuff like lights. Relays break. Wire doesn't - at least not with the regularity of moving parts and/or active devices.
We built all facilities with three colors of 110 outlets. Orange outlets were on an uninterruptible supply (Our standard was 35KVA3 phase, you could use a little one in the coach and run it off the house battery bank). BHrown ones were generator backed, and might lose power for a few seconds while the generator spooled up. White or off - white were building power without backup. Hubbel makes duplex outlets in several colors, they're available at any electric supply house, and I suspect on the web as well.
I've a 1.5KVA unit here which I would put in the coach if I had a need. Pull the gel cells out of it and tun it off the house battery. It only needs to make power till the genset fires up, and it will auto switch. It also has an alarm contact which can be used to fire up the generator if you decided to auto - switch between shore and genset. In your situation, I'd simply wire it to the 110 volt panel and the battery bank, and hook the inverter outlets to it. That way it would give you 110V whenever you wanted, and would automatically follow the genset or the shore power, whichever you were using when you weren't running off batteries.
DOS tip: When you're pulling your wires for 12 volt lights, cables for computer or TV or loudspeakers, or whatever that are hidden wires, double pull them. You'll be glad you did.
