I've been looking at coolers for overland trips and while that's more of a general camping forum question, some of the coolers are so pricey that refrigeration becomes an option. That being said, I haven't seen many folks talk about wiring in a 12v powered cooler into these rigs outside of fully custom stuff which has a new and unrelated wiring harness so the comparison is a little lost. On newer SUVs, like my brother's 4Runner, there's a handy plug all ready to go so most new rigs aren't looking at splicing in a hookup either.

I don't really want to build out the back with a sliding rack system, but adding a port in the rear to plug a fridge in is something I could do. Has anyone gone this route or are coolers the way to go for more daily focused rigs?
