Problem with the 31 is weight... once you add a steel bumper and winch on the front with that battery it gets heavy as fuck. The 31 weighs 75 lbs. I did a group 65 up front and a 31 in the bed box. The 65 had better specs than the 27. Not much but better.
I've been more more than happy with my group 34. It's plenty to run the fridge. I'll upgrade to a dual battery later on if I add a winch. But for now my battery is great.
Ex this deal. They will not drop ship them to you. They would ship them all to me and I would have to ship them back out. Wouldnt make it worth it for any of us.
Just about to go pick up a 65 from Batteries Plus or what ever that place is called. My Second, smaller battery is still okay. I was able to get 7 years of use out of that battery and I'm okay with that. I wonder how much credit was left on that as it was 4 years replacement and 4 years prorated.
I still have one of my original Platinums in my shed powering the led lighting inside it. Its kept topped off by a 20 watt solar panel and charge controller. But its about 8 years old now... bought it in 09 IIRC.
I just shoehorned a 34/78 X2 power from batteries plus in the red truck. It fits but just barely. I believe I have a diehard platinum group 34 or 35 in the Tacoma.
