This was achieved firstly by lengthening the chassis to 129-inches with a stronger frame and suspension. A second approach was to move the cabin into a forward control position, thereby increasing the space within the existing wheel base. The Forward Control Land Rover was first prototyped in 1960 and it was aimed at the commercial market with a standardised three seat truck cabin, although it retained its 4WD and most of Land Rover's existing mechanical options, including power take offs and winches. It was publicly shown for the first time at the London Commercial Motor Show in 1962.
The forward control option was preferred over the 129-inch proposal, and to save time and tooling the existing. Land Rover chassis was used with a raised and altered cab, which was located over the front wheels on a full length sub frame. Due to the extra weight it was initially greatly underpowered, an issue which wasn't fully addressed until fitted with a 3.5L V8 in 1970. Over time, the forward control was modified to address faults, which saw the front axle widened and moved forward, and stronger springs and Salisbury diffs fitted.
