Great thread starter. I don't think we have one yet in the Cherokee/Grand section. I have a WJ, so I'm sure it's a little different than your XJ. But here's what I got.
First mod we ever did on the Jeep was getting the spare tire out of the factory well so we could put tools in there. The tire and jack are on the outside of the vehicle.
This is the overall view of the cargo area.
The Cabelas sleeve is actually a junior archery quiver but works perfect for tire tools, a torque wrench, and a breaker bar. You can also see the come along strapped here too.
Off to the side I have a cheapy air compressor, a bottle jack, and winter insulated welding gloves. I need a better spot for the jack but haven't found anything perfect yet.
Mounted to the back of the back seat are bolt cutters with quick fist clamps. You can also see my axe tucked away under the seat. The chainsaw sits in front of it.
Off to the right side, I have a bag with recovery gear including, d rings, straps, snatch, tree saver, etc.
I built a hinge for the factory tire well cover to fold up so I can leave heavy stuff on the back of it and not have to move it all the time.
Up above in the factory storage compartment on the right, I have some ratchet straps, tie downs, bungey cords, and some bolts/nuts/hardware.
Then inside the well, I have all my basic tools along with a jumpbox and a stick welding kit that can be used with 2 batteries. I do plan on getting a different welding set up eventually.
On the rear floorboard, I have a duffel bag filled with supplies for a 72 hour kit I built for the family. There is enough supplies to last our family of 5 for three days if we were stuck somewhere. It includes military food rations, water, fleece clothing, basic vehicle repair stuff, medicine, signaling devices, toilet paper, etc. This is more for a time where if we slid off an icy road in the winter, we could wait in the car while help arrived. It primarily has clothing to protect us from the cold.
A knife, saw, and fire kit remains in the door panel storage compartment.
And a roof rack which helps a lot with camping gear.
