Well.... I'm inches away from pulling the trigger on a lithium upgrade for my SV34.
Battle Born has a sale right now and the 100Ah LiFePO4 on sale for $150 off. There are a lot of cheaper ones on the market now but from the research I have done their BMS, warranty and reputation is the best in then business. The big thing for me is I leave the coach plugged in during the winter months when its stored in the garage up north and I am down in Florida. The BMS has a cold charging protection system and is a major plus. Many of the LiFePO4's out there don't have that capability.
I am going to replace my four 6V batteries for three 100Ah Battle Born's, a LI-BIM 225 and the Porgressive Dynamics PD9160ALV Converter. I already have a Renogy 30A Solar Controller that is LI capable so I am already set there.
I figure the 300Ah is going to perform much better than the flooded 435Ah and with the lifecyle and warranty, I could transfer them to another coach if I were to decide to sell the SV34 at some point.
I'll hold on to my 6V batteries and converter and put them back in if I would ever sell the coach.
*EDIT*
I just happened to stumble across Big Battery for LiFePO4 options. They also have a 10-year warranty and they seem to offer more power per dollar. There smallest battery is 170Ah and it is on sale for $979. They also have a good BMS with it as well.

Looks like I will be doing a bittle more research.....
