This I the route I would take. A few of these bad boys (probably not politically correct) should do the trick.
Pull up a chair, grab a beer or two and watch a video.

A few of them would give enough power to let all your friends plug in

By my calcs the easily available 5.4kw packs are equal to 4.5 12v Li batteries although they are NMC rather than the LFP that is normally used for RV's. Based on what they go for on fleaBay they work out to ~280$/12v battery.

Starting out with them is better as switching to them would mean changing out the inverter. Most CC's would support 24v. They also need a DC/DC converter for the house elec. A slight difference in actual voltage of 12v vs ~12.8v

This fellow RV’er did a great review on RV batteries!

Having just installed Battle Born LiFePO3 (LFP) 100Ah batteries in our Seneca, I have to say there's no way I'm installing Tesla or other electric car modules (Li-Ion) in my rig, especially under the bed.

Li-Ion batteries have greater capacity, but can pose a fire hazard (which can be rather intense). I'm a battery geek and appreciate that proper charging and properly constructed battery packs negates much of the concern. But one mistake or power event could put your rig (and your lives) at risk - never mind the fuel and propane in close proximity.

LiFePO4 batteries are stable and don't present the fire risk. The discharge curve is flatter and the voltages are lower - which I think suits a 12VDC system better (4-s config=12.8V).

Use something with an integrated battery management system (BMS)! Lithium batteries are fussy about temperature. The BMS will temporarily disconnect the charging or discharging circuits if temperature, voltage, or current limits are exceeded.

Some notes on my experience. BB10012s are EXPENSIVE! but have a 10-year warranty and BMS. Discounted $79/each for four. They fit perfectly in my Group 27 battery tray. The batteries have different terminals so I had to order longer parallel cables for the lengthwise connection. I'll be swapping out the PD4590 Power Converter's Charge Module for a Lithium (-Phosphate) unit.

My lead-acid batteries were marginal from the beginning and I have trouble maintaining them in a storage lot with no AC power access (*). I'm looking forward to the big increase in capacity, faster charging, low self-discharge, low maintenance, no hydrogen venting or terminal corrosion.

* Yes, camping more would have improved the charging situation, but some of us still have to work :-(

790$/BB battery (not 79)? How much solar are you running?

The BB's seem popular. Getting to be more options out there for batteries with Li tech. I'll wait a couple of years yet until my AGM's have aged more to see where Li is at. I've been looking into the prismatic cells.

Discounted to $870 each but you have to ask. I'm running no solar since I have the on-board generator.

Absolutely wait to upgrade if you can. Prices will fall, capacity will go up, and the BMS may become accessibe via Bluetooth or wired. Solar charge controller tech is adapting too.

I looked at building my own modules but I would have $930 in just 18650 LFP cells (new) - no packaging, interconnects, boards or BMS components.

You said it was 79$/each for four so I thought you'd left off the zero. They had a Cyber monday deal for 849$ and there were some blems available for 100$ less.

The prismatics are 100Ah blocks not 18650 cells. The BB's and similar are nice cause they are simple drop in replacements for LA (assuming suitable charging) but everything is available to build custom solutions.

I seem to change my solar setup every year. Somewhere along the line I'll end up with other than the AGM's.

I have ordered my third Li battery @ $430+ shipping, the two I have are working great and so much better than my LA were. My solar is finished as well as the charge controller. Boondocking is much more enjoyable now.
