Question, What is the AmpHour difference between a Group 27F and 31? Would like to stick with the simplicity of the 27F, but since I'm powering a fridge off just the one battery I want to make sure it will handle powering it for a couple days and still have enough juice to start the truck.
I run a fridge (Indel B) on my 31 and it still drains it in 3 days. It was hot so it may have been kicking on and off a lot. I ended up getting a solar setup to avoid that happening again. If you do order the 31 make sure you get the terminals on the correct side. When I bought in this GB it wasn't stated that the part # is different for 4Runners and I had to make all kinds of changes to my stock wiring. So keep that in mind.
