I'm very happy with my 2005 (2004?) 2350. It has the solid rear cap with spare, I upgraded the single battery to a 320amp lithium and added a xantrex whole house inverter (easy to install in the closet floor). Upgraded surround amplifier and speakers, and other comfort things and now it's an ideal motorhome for myself and 2 dogs. Can't believe my Fridge is still working after 21 years and 110,000 miles.
Nice work
How many amps is your DC-DC converter? With no wiring diagram for the pre-2007 PC’s I found it challenging to wire in my Victron Orion. I started with the diagram for a dual battery PC with an inverter/ charger, then traced everything in mine and drew up a schematic. If anyone needs one send me a pm.
I swapped a 140Ah group 31 LiFePO4 into my single battery box without any mods to the tray. At the time that was the highest capacity group 31 available but now LiTime has a 165Ah. I know I could have fit 2 sideways by removing the tray, but it’s adequate with a DC television and LED lights, and we don’t camp in temperatures below 45F so the furnace blower isn’t sucking a lot of Ah’s.
My Norcold is still going strong too. It’s good to clean the hardened old seals with dish soap solution then wipe on a thin layer of Vaseline. Warning: your ice cream may get too frozen!
Staring in 2018 PC’s could be ordered with the Volta Power System. Who’s got one?
