Air pre-cleaner:

That thing on the wing that looks like a short snorkel is actually a Donaldson air intake pre-cleaner sitting directly over a horizontal under wing mounted air filter. Donaldson recommends that the pre-cleaner have at least 6 inches vertical clearance. Why this and not a snorkel? First, a petrol engine will only run when the ignition is above water (unless you have a special water proofed engine). So the intake just needs to be well above the distributor.  Second, is how high road dust is kicked up. Driving by myself the dust level is about even with or a little below the top of the wing. When traveling in a group on a dusty trail, the dust level is well above the top of the truck so running a snorkel inlet to the roof doesn't do  whole lot of good. It is all about keeping dust out of the engine. The Donaldson top spin pre-cleaner is supposed to remove about 90% of dust from the incoming air and sitting above the wing top it is above the dust kicked up during solo travel. Air has mass and when moving, the resistance from tubing and turns in that tubing takes more effort to draw into the engine. Think of trying to breathe through a log straw. It takes more effort from your engine as well. My pre-filter is a sort straight run into the air filter and from the air filter a straight short run into the engine creating just a minimum resistance to air flow while doing a very good job of cleaning the incoming air. Lastly, though a snorkel creates a cool off road image, it blocks part of the diagonal front side view and it makes cleaning the windscreen harder.  Note: I did add a 1 inch spacer to the spring stop block mounted to the frame to keep the wheel from hitting the air cleaner during maximum upward articulation.

Propane tank:

When I purchased my truck it had a five gallon horizontal propane tank mounted to the top of the right front spring outrigger. This tank could only be filled from the top of the side bench inside the truck. I needed a way to fill the tank from outside the truck. So I cut a rectangular hole in the side and used a 109 rear toolbox lid along with its mounting hardware to cover the hole.

It has been my experience that the gas in my built in propane tank lasts for between 3-1/2 to 4 weeks (depending upon weather) of daily camping use before running empty. And it ALWAYS runs dry while cooking dinner at a time when the food is too raw to eat. The plumbing at the tank not only allows filling but switching over to an external tank which I pack on the roof rack.

Rear fuel tank:

My truck has 3 fuel tanks, 2 up front plus a rear tank. The engine is fuel injected which means a fuel return fitting had to be added. The system is set up so the two front smaller tanks are transfer tanks. Fuel is pumped from a front tank into the larger rear tank when the fuel in the large tank is low. So a transfer fuel fitting was also added to the top of the rear fuel tank. The filler assembly is from a Defender high capacity pickup.  The bottom cut of the recessed filler part is right at the bottom of the toolbox. Cut so the the toolbox floor remains. Of course you should not try to mount the filler assembly until after the tank is mounted.

The 109 regular has a pathway for an optional rear PTO. There is a hole in the second to last crossmember for the PTO drive shaft which causes part of the crossmember to dip down. The bottom needs to be cut off so the crossmember is straight then a steel plate welded to the cut off section to seal the hole. Other than that, there are a couple gussets that need to be ground down a little before the rear fuel tank can be installed.
