Yup, owning an alarm co. in CA, the Electrical Union pressured the government to require us to have an electrician's license to install and maintain smoke detectors. So, I got my C-10 license . . . I wouldn't want to live in a house I wired, but otherwise I know what I'm doing. Sounds like a nice big rig you have there. My little 26.5 foot LD is set up a lot different. 400 watts of solar on the roof, 3KW inverter/charger, 470 AH of battery capacity between two battery banks, so I can run anything on board, including the microwave (but excepting the air conditioner), without running the generator. To make up for that, as we almost never "plug in" to use AC, we have a TurboCool (aka swamp cooler) on the roof. That way it takes very little energy to keep the rig cool. It's pretty much ideal for how we use it.
470 AH of battery sounds like a lot. But are they LiFePO4 lith batteries? Besides the fact the lith batteries last a lot longer, I like the fact that they keep the voltage nice and high until they are more than 95% discharged. And can accept deeper discharges than L-A batteries. It's best to not discharge L-A deep cycle batteries much below 50% which is around 12.1 resting (no load) volts.
I only have 100 watts of solar on the roof of my Class A and 80 watts on the roof of my class C. But I have several external panels which I have not used since my trip to the Everglades and also at Organ Pipe Cactus Nat'l Monument, AZ on the way back. I am not picky about where I stay. I can be at a full hookup RV park or be boondock somewhere.
I can also run everything in either of my RVs but not the A/C. At least not for long! But neither of my RVs were purchased that way. I had to put in the stuff myself for the higher power for when boondcked.
Your swamp cooler sounds like a great idea. Did you add it yourself or was it stock with the LD?
I do most of my RVing in the middle of winter--to warm places. The Everglades can get above 90°F. in December and even the nights are quite warm. I was boondocked there last December. That was a 3-month RV trip where I visited many states I have never been in before. And spent a week in many, such as GA, SC & LA. But I spent most of the time in various parts of Florida.
My Class A is exactly 29' 11". That means it can go anywhere with a 30-foot limit such as many federal boondocking parks. I wanted the smallest Class A I could buy, but there were way too many issues with the Thor Axis . Not enough storage space. Compressor only small refrigerator that drew 8 amps on 12 volts. So I paid a bit more and purchased the Entrega Vison 70 instead. Now I feel it was the perfect size for just me anyway. I wouldn't want it shorter or longer. I am quite happy with it. But I still had to add to the house electrical system.
I guess I can say my new RV has 500 AH of battery. 200 AH in the stock L-A batteries and the 300 AH I added in the lith batteries in a separate system. I also have two inverters that I can use at the same time, a 1200 watt and my 4KW watt one I added. But I would need to change the CB for more power if I really need it, which is very unlikley. Both inverters are true sinewave. Works well for the 1500 watt MW oven or hair drier that draws about the same. But the added stuff is also for my ham radio stuff that likes to see around 13 volts or so.
