Thanks for your interest guys I don't think any of you can see the other forum link as you would see I have already been thinking of many of these ideas.
The dumper was my first thought but very slow and hard to find a front wheel steer version.
Jeeps etc are not perfect because I want a rear engine and trying to keep it light so don't need 4x4 just RWD and rear engine like the small ATV buggies you see about these days. However to look right is should be capable of having large OD wheels and hence some decent bearings and hence large PCD like a transit.
A range rover would give me 5x165 PCD and nice cheap 16" LR tyres but the struts and hubs are not as plentiful as a Transit.
I think Transits are awesome vehicles and have so many variations also I think the PCD is 5x160 so quite close to a LR wheel rim. Anyway I think a Transit 16" rim may be good for a large ATV type tyre, I would prefer a WW2 style bargrip as in the photo above.
Good photos can be seen here

The Dingo was copied by Ford to make the Lynx Scout Car and also by the Italians who then supplied them to the Germans.
Lynx Scout Car
A closely related vehicle, the Lynx Scout Car, was produced by Ford Canada in Windsor, Ontario. The Lynx took a Dingo-type hull and set it on a chassis with four wheel drive taken from the rear mounted engine. While the engine was more powerful than the Dingo's, the gearbox and suspension were inferior. 3255 units were built, entering service sometime around 1943.
The Autoblinda Lince ("Lynx") was an Italian armored car used by the Italian Social Republic between 1943-1945 during World War II. The Lince was a copy of the British Daimler Dingo and was primarily used for reconnaissance. Its armament consisted of a single 8 mm machine gun. Some 250 vehicles were built in all. The vehicle was also employed by German forces as Panzerspähwagen Lince 202(i).

The Lynx seems to have used 9.00 X 16 tyres.
I see the Transit has used 16" rims

You can see the Lynx used leaf springs not the coils like the Dingo.

The WW2 Dingo only had a 55 BHP engine which was straight 6 x 2.5L you could get that from an old 1.3L these days just slung in the back so lighter than the Transit unit.
I think this could weigh in at about 800kg if made light.
