Is this a possibility?

Here are the components of my solar generator:

1) TM-2025-RV Battery Monitor Package - pkg includes 35ft of wire and 500amp shunt

2)Morningstar ts mppt - 45amp mpt charge controller

3)Caster Wheels - on bottom of generator so it can be moved

4) Batteries - 4ea 250 ah full river 6 volt

5) Samlex PST-2000-12 Pure Sine Inverter

6) IOTA Battery Charger - 12V 55A - If I need to use a generator this charger should charge the batteries more quickly.

7) solar panels - 2ea - 270 watt monocrystalline from Solarworld

Is this something you've assembled yourself? Or purchased as a package?

That is a good list of components IMO, and what you propose I believe will work, with the exception of running an A/C. That is not enough battery capacity to run an A/C for long, and not enough solar capacity to replace the state of charge in a day. I think that inverter would run a 12.5 A/C just barely. It is a 2kW continuous, 3.5kW surge. 500AH of battery won't sustain that for long.

I purchased all the components and had another guy put it all together. He had a local metal fab shop build the equipment box and frame. I think you may be mis-understanding my intent. For 110 volt needs, yes, I will have an extension cord ran between the solar generator and RV, however I understand, and do not plan to run all 110 volt appliances continuously or together at the same time.
My real intent is to see if possible to directly link my solar batteries and RV batteries so that I do not have to turn on the inverter in the solar generator, and also the converter in the RV to recharge the 2ea 12 volt house batteries.

You could be correct in the earlier message that my solar generator will not know I have 2ea extra batteries attached, and I guess that would be OK because I can monitor them via the RV house light panel inside to see their state of charge.

My main question/concern is if you have 4ea 6 volt batteries in series/parallel to yield 12 volts at 500ah..... can you then safely link them to 2ea 12 volt RV/house batteries? My goal here is to eliminate the need to run the converter in the RV to recharge the 2ea house batteries. But, I don't want to damage the solar generator batteries or any batteries for that matter. Please note that the 500 AH is the total capacity of the solar generator batteries and I plan to not discharge them below 50%.
