It ain't tires. Unless you have a very specific, special need for them. Heck, most of the tires ya'll are running, are a joke to me.
I can choose trails that lame OEM tires work fine on. And forego softer trails for later. I can also pick a mild hybrid tread for better slab use. And chain up, in mud.
I'll concede that proper tires are priceless, but we all started with thin wall garbage, and did fine.
It ain't a lift, lights, or nav. Subaru's get by just fine, I sleep at night, and sat nav is just about useless off road. It ain't kitchen or sleep. We're fat, and ground tents still rule.
For me it's lockers. All 4 tires spinning the same speed no matter what. Complete game changer.
