After taking all the advice here and doing plenty of research I think I've made a solid list of items to put together a good working simpler solar setup.
tell me what you think.

Trina TSM-230PA05 230-watt solar panel

12 V 245 AH AGM 8A8D

1500 Watt Pure Sine Power Inverter 12 Volt by AIMS. With Free Remote.

Blue Sky Energy Inc. | Solar Boost 2000E

While some of the components are stout, I'd like to be able to rely on them for long tern use.

If you care to suggest something different, please chime in.
I'm thinking this will be plenty of power for 2 possibly 3 days if the sun isn't out. Of course knowing the sun isn't doing it's thing I'd conserve with extra care.

Know of a better price somewhere?

And possibly instead of a microwave for indoor cooking I was thinking of This And it would save a whole bunch of power.

I'm not the solar expert but I do a lot of cooking on propane stoves with the Scouts. I know alcohol stoves are the most efficient when you are a minimalist backpacker, but the stove you picked out is a little pricey and are the cartridges readily available if you are traveling? From the website, it looks like your cartridges will be over $60 each.

You may want to look in to something like this: Amazon.com: GASONE Portable Gas Stove CSA Approved: Sports & Outdoors

Or even the old dependable Coleman two burner stove with propane tanks that you can get anywhere:

Start with the 158 pound battery. That means your usable energy reserve is about 1800 watt hours (12 watt hours per pound). The 2 or 3 day battery reserve means that your energy use will need to be well under 1 kWh/day. That isn't easy, especially when you start talking about occasional microwave use, RV furnace, media center, or lotsa-lights.

By the rule of thumb of a watt of solar per pound of battery, you have plenty of solar to cover that battery.

The daily energy harvest from a 230 watt panel should be at least 460 watt hours in most conditions so that is getting close to the reserve capability estimate, too.

You'll still need a weekly bulk charging capability of 4 watts per pound of battery, which could be a 600 watt inverter (50 amps at 12v). This is a battery maintenance thing for best battery service.

A 1500 watt inverter should handle most AC needs and the 2500 watt surge should handle most startup conditions typical of the more power hungry appliances. The 125 amp input current will need careful attention to wiring and the connection to the AC circuits will need some sort of switching arrangement.

The 2000E is a good charge controller with a long history so it should work well.

The big item missing is something for battery maintenance. When the rig is not in use, you need to have something on the batteries that will assure a full charge and also apply a sulfation inhibiting technique. This is where a lot of solar systems suffer. Float or trickle charging just doesn't cut it anymore IMHO.

more on the 'rules of thumb' at 1 to 10 kWh battery systems – rules of thumb.

The wiring and connections can play an important part. I don't think you need to go quite to the 'Handy Bob' level but proper wire size design, lengths, and connections can make a difference. The inverter also needs input wire impedance considerations, too.

I don't think it will work. There's rain in the forecast.
