I’m in the same moment with Hull 292, a 2017 sweet Ollie. How much is your upgrade expected to cost? I’m thinking, new 3000 Xantrex, cables, around 400AH of Lithium, new cables, fuses, bus bars, and someone smarter than me to put it all together. 

I have not added up the total. I believe I am less than $5k all in.  Many hours of my (unskilled) labor, though.
 

 This upgrade (just completed) included (3) BB 100ah batteries, all Victron components.  MP2 inverter/charger, MPPT solar charger, Cerbo GX plus display, Lynx distributor (fused bus bar), Lynx smart shunt, VE Bus dongle, DC-DC charger - plus a lot of new/ cleaned up wiring.  I rearranged the factory 120 volt wiring to have all power pass through the MP2 before going to the C/B panel.  I can now run the air conditioner off the 3000 watt inverter. 
 

So far, everything tests good.  Have a week of camping planned next week at SNF to really shake it down.  
 

Anyone in the Atlanta area needing a Xantrex 2K inverter/charger or a Zamp solar controller - let me know.

Great info. Thanks. Just so I’m clear, you can run the AC off the 300ah batteries through the inverter?

Yes.  I have the Houghton/RecPro 13.5k heat pump which draws quite a bit less than the Dometic turbojet penguin.  I want to add a soft start to the Houghton to reduce the inrush current.  
 

I have no idea yet how long the Houghton will run off the batteries, but it will start. My hope is it’s long enough to cool the trailer down at a lunch stop.

Hi all and thank you all for the good advice in getting a professional to put them in for me. I could easily have dropped a battery. Yiks and then got burned with battery acid ! I just picked my Ollie up from my local trailer place (it is actually a horse trailer repair place I use but same principles)  and got the new 2X 230Ah batteries installed. They fit perfectly in the battery tray. Very pleased!

Looks like you decided on LiTime LFPs, if so good decision! This was my final configuration, also to include a Victron SmartShunt and ANL 250-Amp fuse.
