I'm on the same mission. It sounds like you are going the route of having a massive electrical setup with solar and a generator for support. There are plenty of places to help you calculate your electrical needs, so I'm going to discuss the diesel route instead. I'm going the other way with no 120VAC loads, and diesel everywhere possible instead of 12vdc in the few places I need it. Here's what I've found and what I'm doing. It's not a cheap endeavor. Can you do it cheaper than I am. Sure, you can buy Chinese goods. I'm not going to go in depth about the electrical options because those are the same for everyone.
1. Heating:
a. Diesel coolant heater piped to hydronic heaters. I bought a Webasto Scholastic NIB for $1600 Ebay, I've seen some other deals if you know where to look. There are other brands of course (Espar, Planar, ProHeat, etc...), or you can fork out the cash for a truck APU that includes heat, power, and AC.
b. Diesel foreced air heater. Webasto, Espar, Wallas, Chinese... People seem to love these.
c. There are also some small diesel boat heaters/stoves like the Dickinson Newport, and tons of freestanding models like the Refleks. These can be really beautiful.
2. Water heating: Diesel coolant heater. As above. Look into water heaters designed for marine applications. Many include an engine coolant heat exchanger. Some brands are IsoTemp, Whale Seaward, Kuuma, etc... Most of these include an 120VAC electrical heating coil. I'm swapping mine to 12VDC so I can run it sans inverter. $300 for the water heater.
3. Fridge: Obviously you can't go propane. So you can spend as much or as little as you want. You can even buy marine refrigeration components and build the box yourself if you want. I'm going with a R134a chest freezer (harder to find now), and replacing the 120VAC compressor with a 12VDC Danfoss. Again so I can run it sans inverter. Some modification to the thermostat, and I'll have a 12VDC efficient fridge. $100 for the used freezer, $300 for the compressor
4. AC: Like I said above you can get an APU (Auxiliary Power Unit) from a semi truck that has a small diesel motor that runs AC, or if you have enough electricity (solar/generator/nuclear/etc...) you can run whatever AC you want. No AC for me until/unless I find it necessary. I do have hope though with some of these newer efficient units... Used APUs run about $2000 depending on features. New are $10-15k.
5. Cooking: There are plenty of options for electrical cooking but again you need the electrical capacity and generation to run those. For diesel, there are very few.
a. Natural draft diesel stoves. These operate like wood stoves, except they have a pot burner. They are almost exclusively designed for boats. There are styles that have ovens (Dickinson), there are styles that only have room for a pot (Refleks). These like to be lit once and run all out for the entire season, you're not going to bust out a quick lunch with one of these.
b. Forced air diesel stoves. These look like induction stoves, but are burners with a ceramic top. Wallas makes them for boats and Webasto licenses them for RVs. Still has to heat up, but not the same extent as above thanks to the forced air burner.
Diesel will cost you. A new Dickinson/Wallas/Webasto will run you $2000. I found a used Dickinson in Washington for $500, and had it freighted to NM for an additional $400.
c. Diesel camp stove. Very few models that advertise they can run diesel, and from my discussions with the stove gurus over at classiccampstoves.com it is not recommended. Hard to light, hard to clean, smokes like crazy. They recommend just sticking with Kerosene, white gas, etc... A few MSR models advertise diesel, one Coleman, a couple BRS, and some older British, Swedish, German military stoves. There are only a few other options that I've found and they are obscure. $100 - $500 depending on model.
Happy Hunting
