I wonder why it is this long ?

Think it's to make it easier to keep the line straight, there's a mirror on the bracket at the front to follow the white line on the ground

It also looks like the paint discharge is in the center of the rear??? So this machine must of had to straddle the previous line??

Looks like the big sign over the cab would have been for the oncoming traffic?

Grandad listened in trig lessons at school.

The back axle is the pivot point. A 100mm deviation of the front wheels from the line with a 10 metre wheel base and a 2 metre distance to the spray nozzle out the back will make the line wander 20mm. If it had a more normal 5 metre wheelbase the line would be wandering 40mm.

The long distance from the driver to the front gives a much better "aiming point" and deviations are picked up very quickly. The same track deviation with the same eye and driver reaction will correct in half the time on a long wheelbase compared to short. One of the main reasons you never see a sniper rifle with a short barrel or it is much easier to keep an aircraft with a long nose straight on the runway compared with a short nose.
