Mitsubishi Canter/FG 140 4x4 buildup
We are building a Mitsubishi Canter/FG 140 4x4 for overland travel.
Main project site:
Comments and feedback are welcome.
An Interesting well thought out conversion with a very good use of space - with a GM/Ford/Dodge dually you would have no room for the bikes and as you know a trailer on a long trip is a real liability with a long wheelbase.
Im sure you are aware of the ramp angle you have - the side lockers look quite low slung - are the fuel tanks recessed up a little so they are not the first thing to touch down ?
Also over Bad washboard/corrogations is there/will there be any contact between the bigfoot and the bike garage area - is there much movement ?
I couldnt tell from the photos - but is the chassis area around the fuel tanks reinforced at all - there will be a lot of loading on this area - or is it pretty beefy ?
Other than that - the Winch Cables- with a fairly heavy vehicle (any vehicle for that matter - but heavier vehicles load the cables up if badly bogged) I hate to see wire rope used these days - Cables IMO are bloody dangerous - having seen quite a few part and cause a lot of damage (fortunately only to vehicles)- they also splinter,kink,freeze up (and your hands), are heavy and you need heavy roller fairleads which dont do anything for approach/departure angles.
I would consider swopping them for some Synthetic Rope - stronger, easy to handle and spool in, wont freeze, doesnt kink, is much lighter and if it does break it will go dead and wont whip like wire rope - much much safer.
use it with alloy fairleads - probably save you 100 lbs ish in weight between the cables and fairleads.
Try these guys:
Keep us posted with any updates/testing - great website !!!

The small tyres and modest angles/ground clearance will restrict your options for exploring off the beaten track. Can you fit larger diameter tyres ? Also, do you really need two bikes ? You could save a lot of weight by taking only one. As for tyres I would choose Michelin XZY over any other type for this type of journey - they are pretty well bombproof. The cab access step looks a bit vulnerable, maybe consider a folding (Land Rover) type ?
Good luck with the trip.
We plan to put motorcycle shocks on the rear of the pivot frame to dampen some of the lateral motion by the camper & upper boxes (which are also mounted to the pivot frame.)
At the last possible moment I had our fabricator modify our spare tire storage compartments to fit the XZYs, but we haven't tested them. I have my doubts they will fit laterally in the compartments.
The XZYs are 3" taller and would give us 300 lbs. more axle capacity on the front. They are not readily available in the US, so we would need to source them out of Canada, most likely as take-offs of their Army's G-Wagons, or from NZ/OZ or Europe.
XZY's are available in the UK new (ex military, but brand new) from VASS. About £50 apiece. They are also available in 17.5 and 20 inch sizes (but not from VASS).

The FG is basically a delivery truck capable of use in unpaved areas. We see it as a two-track type of vehicle. Roads of a type that in the US would be ungraded fire roads in the Western mountains. The small wheel size, dual rear wheels and limited ground clearance inherently limit the chassis. Our weight and ~59"/ ~150cm CG location also limit us in terms of roll angle.
Having said that, we know of very experienced 4x4 people who are out in this chassis who go to some amazingly rugged places with their FG. We are not experiened 4x4 people, so we'll take it as far as we are comfortable and then get on the two dirt bikes we carry inside.
So, not limited to tarmac, but certainly limited, at least for us, to reasonable two-tracks. That was our design brief for this project, so we are happy with those results.
We've spent a lot of time motorcycling in developing economies, so we knew the type of roads we were building the truck for. We're not looking to go where no vehicle has gone before with the truck. We'll get on the dirt bikes for that type of work.
And stepping back a couple of levels of abstraction, the FG is not a poor man's MOG or even a Defender on steroids, and I think that people can set themselves up for disappointment if they mentally develop that implementation model for this chassis. For what it is, it is a fantastically capable platform, but I think it is important to work within its capabilities and potential.
I think I am going to like the idea of a comfortable, versatile mobile base from which to continue exploration on two wheels.
You've certainly done a great job and it shows in the pictures and descriptions.
As far as I am concerned, having grown used to carrying only the essentails, I can't even imagine how great it would be to achieve such a high level of autonomy.
Doug, that vehicle looks quite amazing - hell off a job building it. Is that a "S Class type" infra-red camera arrangement in the cab in the picture?
And the specifications of the data storage and sound system (alongwith everything else) - wow! Your project is bigger in many ways than most peoples houses :-)
Can I ask with such an obviously valuable vehicle and kit how do you approach the issue of vehicle security and not having someone drive away with it...
Best of luck,
Actually, we've found the world outside the US to be a very welcoming and generally safe place. We rely on using our common sense, listening to our gut and taking some reasonable precautions.

Far too much info for me to read through, so you may have sorted out a good solution, but my thought was how easy it would be to smash in one of your windows and climb into the back.
Grills or reinforced windows might be a good idea for when your out on the bikes. Also your front spot lights might not last long in places I have been (though again I don't know where your plnning to use this).
Just a thought...
