Haven't run into many Grizzly Bears in Texas, so no automatic weapons on my bumper.
But, My Bumper on my Isuzu Rodeo is a lot different than many. When I built the bumper I made it out of 4"x4" square tubing. I ran the mounting plates all the way through it so my recover rings tie to the frame rails through it.
That left me with a lot of hollow tubing. I tapered the ends and that still left a lot of hollow tubing inboard between the frame rails. So, me being me, I made some lids and cut rectangular access holes in the top of the bumper. Had an old aluminum running board laying around so that's what I used for the lids, because it made a great traction surface for standing on the bumper. A few quarter turn "D" ring fasteners and it made 2 pretty nice storage places. I carpeted the insides of the compartments to keep the rattle low key! One side carries the Jumper cables and the other side stores the tree straps and extra winch pullys.
I recessed the license plate between the 2 compartments. Then put the license plate on a hinge so it swings down like the old cars from the 60'. Behind it I mounted a plastic cutting board and mounted my connectors for my trailer wiring , including fuses for the electric brakes and power lead to the trailer battery. Makes trouble shooting wiring issues on the trailer a breeze.
I then mounted a 2 inch receirver hitch under the license plate and a 4 prong trailer plug in and a 7 prong RV style plug in the hitches gussets. Like I said, for my camper trailers brake system.
Most people never notice that the traction plates are removable and that there are compartments under them.
And since I flat tow my Rodeo behind the RV a lot I added extra brake lights into the bumper that work when I'm connected to the RV's lights. Full Floating axles with dial out hubs on all 4 corners make flat towing simple and puts less wear on the expensive differentials and transmissions. I've actually towed it for over 60K miles so far.
In the picture the license plate is lowered to show the electric connection plate. Not all the connections were installed at the time of that picture, but that's where they are.
As for the rest of the back side of the Rig, there's a lot going on back there. I have a single swing out arm that has the spare on it. And two military styl can carriers. One I carry water for the kitchen sink, and te other I usually carry an old 60's German Military style food can. (It looks like a gas can only it's insulated and the whole lid pops off.) I use it as a dink cooler.
The tire carrier also has my ARB compressor in behind the spare so it's easy to work on and there is a air hose connector should I need it to air the tires back up. Especially if my CO2 tank runs dry.
And when the spare tire is swung out I have a kitchen complete with running water, 2 burner coleman stove and a cutting board table for food preperations. Then there is the slide out freeezer right there when the tailgate is down. I have a small portable water pump that plugs into the ARB's wirig harness so my sink was water pressure at the valve. I just drop the hose into the water jug, and Bob's my Uncle. I do have a hot water on demand heaster, but have yet to use it on the truck. We use it on the little pop up camper trailer.
Now as for how do I carry extra fuel you might wonder? Isuzus used the same frames on most all of their pickups, Troopers and Rodeos. The Rodeos and Troopers use a rear mounted 26 gallon fuel tank and the pickups use an 13 or 21 gallon fuel tank (depending on the truck) that runs under the passenger side between the driveshaft and frame rail. Most of the bracketry is welded on at the Factory, So it's not a big deal to mount build the one missing bracket to add a pickup fuel tank to the Rodeos or Troopers. And the Pickup ones have a skid plate uinder them just like the rear mounted ones.
So I run dual factory made fuel tanks under my Rodeo. Keeps the weight low.
And my fuel tank selsctor valve also switches between the 2 fuel gauge sending units, so I always know how much fuel in in each tank just by switching the fuel selector valve to either tank.
I built a "Y" filler neck tube that makes it easy to put fuel in either fuel tank from the same filler neck. Point the nozzle forward and fill the pickup tank. Point it rearward and fuel goes in the rear tank.
I have some better pictures on my other computer I'll try and load up from a little later, if anyone is interested in all that stuff.
Almost forgot, I have a back up camera that shows the trailer hitch so I can load up my camper by myself easier. SAves a lot of damage in parking lots too! Blind Spots like crazy.
It works for me. And I've been building and playing with this Truck since 1993. So yea, there's a lot going on.
