Renault Premium 430

Renault Premium, a rare beast, 6 x 4 on air suspension, a really heavy duty truck. We ran it for a while, took a rear mounted crane off and now we cant get it to move, probably something simple. We believe it is a ECU in the gearbox. We are selling for spares or repairs, as you can see its on almost new tyres right across the double drive bogie. I reiterate it does not drive !!!!
