Lifeline GPL-27T AGM Battery Upgrade
Late last week I placed an order at bestconverter.com for two Lifeline GPL-27T AGM batteries to replace the two NAPA batteries the dealer installed in my 2016 Northern-Lite 8'11". The big brown truck...

I think maybe the finicky nature of AGMs is being overstated. They will benefit - a little - from a heavy charge occasionally. It will take them longer to reach 100 percent state of charge at 14.1 that 14.4, but they will get there. I agree with the advice to use the flooded setting (vs. gel) if those are your only choices. Mainly because the float setting for gel will be too high for AGM (13.8 vs. 13.4). A temperature compensating controller is a very good idea as well. You do need to fully charge them periodically, and never store them partially charged.
Lifeline AGMs are a high quality AGM, but the chemistry is nearly identical to other AGM batteries. The other different choices in AGM are foamed carbon (Firefly) or thin plate (Odyssey). Only foamed carbon lead acids tolerate begin operated in a partial state of charge for long periods, even flooded batteries suffer from this. But flooded batteries can be equalized to reverse the sulfation (to a large extent) while AGMs are ruined by that procedure.
