27f AGM upgrade on a 22’ OR. Do I need a new battery tray?

I won’t be into anything too gnarly, but I put some good miles on the truck for work and fun. I would like to upgrade my battery to a 27f AGM that will support a full time, on board fridge and was wondering:

1- how necessary is a beefier tray to protect the mounting surface and structure?

2- where the hell can I find one if I do need one?

 

Although not an AGM 27, here's my Group31 AGM battery Install

 

I was in the same boat. You can order the 27f Toyota factory tray from OEM Part Source. The tray itself is the same quality as the one you already have, just bigger. The biggest concern is the supporting understructure, which will likely crack if you do any heavy offroading. Unfortunately not many good options to beef that up without extensive work. If you're mostly pavement pounding or towing, you'll be fine.

Here's a copy and paste from my order

Thanks, friend.

The 27f is a bit lighter and only 10 amp hours or so less than the 31 so I think I’m sticking with it. I originally planned on a 31, but I’m only running the fridge (

Iceco VL45), no lights or other fancy doodads. I am adding a Lensun hood panel so I’m hopping shedding a few lbs will be helpful since I’ll be topped off regularly.

 

Thanks a ton, homie!
