I actually have a Barricade Trail Force HD front bumper and will be getting the rear bumper within 6 months. Also looking into getting a leveling kit as well...but not sure how any of that effects the Hi-lift?

 

The OEM bumpers and probably the Rubi rock rails aren't suitable for a Hi-lift. You'll bend metal and/or plastic. You can test the Hi-lift on your aftermarket bumpers to see how it works. But, you still have to jack very high to get a wheel off the ground. A bottle jack under the axle is way easier and safer.

 

You will want an air compressor so you can lower the TP for a more comfortable ride off road. Don't skimp on this purchase, for stock tires I recommend a 400p at minimum if you go larger consider an ARB or similar output.

Winch- never know what will happen out there or who you might need to help so a winch is good. Warn makes a winch that combines in a air compressor so that can kill two birds with one stone.

Recovery/tow strap(s)- at least one 50' strap.

Basic hand tools.

CB- never know if you will be with a group or need to call out for an emergency. Range isn't that great but better than nothing.

SPOT- if you go by yourself you can at least notify people where you are and if you need help.

Gas cans- went the rotopax- smaller, easier to manipulate than attempting to pick up and manage a 5 gallon gas can.

Hi-lift- even if you are stock this is a good idea as the terrain is not even and your stock unit will most likely NOT help you out there.

Tire plug kit- nice to have for you or someone else out on the trail with a puncture

 

I've seen some people talking about axes. I had to help get a motorcycle up a mountain side deep drop off on why 129(the Dragon). They couldn't clear the trees and I had an Ontario knife company SPAX rescue hand ax on board. it worked great to remove small trees in way of the the winch path.

 

X2 on the tire patch kit (plus extra plugs) and the bottle jack (and I carry a 4x6x14" block as the base for the jack). While I carry a hi-lift, I hope to God I never have to use it (and as others have pointed out, you can't use it on the OEM bumpers).
I carry a folding pruning saw rather than an ax for clearing fallen trees.
Also, a 30' snatch strap and a 6' tree saver strap (which I use more often to drag firewood to camp than to rescue stuck vehicles)
