Lithium batteries with which charger/inverter?

That's cool; I really love and appreciate the input.   

But, please note that the above example was everything used to the MAX; including double the time it takes to boil water and use a blender.  
The above WH include forgetting to toggle the inverter, fan on MAX output, etc.  I highly doubt we'll use a 90 cfm fan on high for 24hrs. 

Our goal:  Travel around visiting US Parks, hike and mt bike.   
We will rarely be idle for more than a day, so in addition to solor, we'll have the system running off of the car too. 
Our plan includes looking at this as a camping trip that happens to have come portable power.   So, we will be using a camp stove & grill as first, relying on battery power 2nd.   

We plan on shore power 1-2 per week via staying at campgrounds.  For us, one of the most beautiful parts of our plan is that if the weather is looking sucky for more than a day or so, we just drive to somewhere nicer.   

I am new to solar, but as a contractor I use Dewalt Li tools daily for work.  The Dewalt Power Station which is much smaller battery wise (runs on 4 20-60v 5-9ah batteries) that can run full table saws & miterboxes for 100's of cuts (usually 1/2 day)  which is a lot of On/Off surges.   Now, I get that the Dewalt stuff is 20-60v batteries, so that voltage comes into play, but IMO it can't make that much of a difference. 

Again, I get that some of my constants add up,  but our current planned system is based on double what I think our avg. use should be and basically 1 to 1 for our max use for a day. 

That all said, I think that I have my wife ready to buy up 1 more battery and reaching for 500w of panels, 600 if we can squeeze it.  We are space limited and since i don't have my fan in the roof yet, I can only guess a real layout for the panels.  

Again, I really appreciate the feedback and I hope all of this helps others figure out their system also.

Hah, I think there is a misunderstanding here... 

My initial question about the I/C is that none of the I/C that I've seen have LiFePO4 settings listed on them; so, is it ok to use them anyway with teh closest AGM setting. 

- The Admin is saying that a standard I/C does not charge a LiFePO4 battery appropriately when connected to shore power.  

- Based on the Admin's response, I've located a dedicated LiFePO4 charger that I'd use ONLY when I connect to Shore Power and I'll ditch the idea of a I/C for a Inverter only.    Otherwise, the ChargeController will take care of everything while off shore power. 

I have 448AH of AGM and last winter ran 320W of solar (640w for this winter). With the 2000w PSW inverter it had no problem running whatever I wanted turned on. The only large kitchen loads we ran was microwave & blender. After using lighting/TV overnight and appliances in the morning I was back to full by 11am in South AZ with the panels tilted in Jan/Feb. We have an induction cookplate but only used it on hookups as we have a propane stove, maybe this winter I'll try it on battery with the extra panels.

Sounds like you're doing pretty much the same as us except we have a 40' 5th wheel we haul down from Ontario for 4-5 months in the SW. Any issue you would have will crop up after 2 days of overcast, then you'd need to move to an electric site. I think you'll be fine with 400w solar and 2 Li's. Having 3 would be better but only for longer low solar support. The Dometic 75 cooler/freezer can run on 12v which would let you turn off the inverter when you aren't using the 110v appliances

Yes that is correct. You can not use the inverter charger to charge your LFP batteries, however, you can definitely use the progressive dynamics charger separately when you're connected to shore power. This could be an alternative/advantage when you're on shore power on not relying solely on solar.
