[Nightmare]

I've been researching an upgrade to our RV power system. I'm still not sure what I want to do, after a visit to the local RV shop I'm in some sticker shock.

Our RV and the 'stock' equipment

2017 Thor Quantum GR22
- 2 of the Interstate 12V RV batteries (these are 100% shot, multiple dead cells)
- Onan 4KW Generator
- Whatever stock charger/converter that Thor installed (I'm sure it is cheap)
- 5100 Series Transfer Relay

I thought I would be able to just install a new Inverter next to the transfer relay, but the shop guy tells me that isn't the 'right way'. Sounds like they charge about $2,000 to install the inverter with a separate sub-panel (so the things I don't want the inverter to run are separate.

I planned to get a big AGM battery (200+ AH), but he tells me that it won't work much better than the Interstate 12v (discharge % and stuff like that).

They suggest either 6v Deep Cycle (which may not fit under the step) or go FULL SEND and get a Li Battery. Which requires a new Charger and possibly other upgrades.

I really don't think we will be boondocking for more than a week at a time. I mainly want the ability to run the TVs off the inverter. I guess I could just buy a portable inverter...

So what do you guys have? And if you are willing to share the cost.

Thanks
