- S_DavisExplorerI guess then if I need more power I can stack another Outback and add more batteries later.

I haven't done this but it might be a wise idea to divide $ by amp hours and see if there's a valid difference between the two BCI sizes.
Four 4-D's make sense. Suddenly the last 20% of charging means not 10 amps but a 40 amp charge rate. This makes the running of a generator much more valid. With my wet Rolls batteries 100 amperes is quite near where the specific gravity readings tell me to revert to float. And that is = to 2,800 watts.
Weight, space, and initial cost are the counterpoints and with AGM it is vital that the first 90% of your charge regimen reaches 20% of total amp hour capacity of the bank IF THE BATTERIES ARE DRAWN DOWN to 50% amp hours remaining. Means discharging to deep cycle exercise. This high amperage can be reduced to 10% if recharging occurs when remaining ampere hours total 60% of total capacity. Around 75% remaining amp hours the necessity of a minimum amperage recharge vanishes but the bank requires a full recharge every 2 weeks or so.
A 36 amp Megawatt feeding off a small 1000 watt generator for 5 hours will take the sting out of this top charging. Let the gen run out of gas as a foolproof timer. Any time the regular onboard charger dips below 40 amps charge, revert to the Megawatt and tiny generator and save a lot of money in fuel. This only happens when top charging.

I am planning on using the 120amp charging from the truck and then using a Outback VFXR2812 that has a 125amp charger. Bulk charge at 14.4 from the truck and Honda 2200 watt gen or shore power and Outback for fully charging. So should I stick to just two of the 8D with a max 125amp charging rate? - MEXICOWANDERERExplorerI haven't done this but it might be a wise idea to divide $ by amp hours and see if there's a valid difference between the two BCI sizes.

- MEXICOWANDERERExplorerI really endorse your decision to seek the reputation of a seller of AGM batteries. Too many complaints of batteries of old stock showing 12.50 volts or less. It's a vendor's responsibility to ensure they are vending a maintained product. IMHO you are purchasing the best and the 'best' will easily last 600 full range cycles which translates to what...10-years of vacation boondocking, minimum? Lifeline has their act together with their online user manual. I am rigid with my own 31 about maintenance and it has paid off handsomely.

- I just ordered 2 GPL31T from Pasco/Stein battery.... they priced matched a guy about an hour away.. when I went to pick them up, they had ordered 2 of the GPL31XT by mistake....
I told them they were different, but they gave them to me for the same cost...paid $320.00 ea
Great people to deal with.
Amazon was showing them at $474.00 - MEXICOWANDERERExplorerShipping is eveything
