Whilst the information on the Perentie Project is elsewhere on REMLR, to help clear the confusion about some vehicles, a page with information about "Prototypes", "Trials" and "Development" vehicles involved with the development of the 6x6 and Project Perentie seemed to be appropriate.

There is often confusion as to what some vehicles surrounding the project are, so this page should help to clarify. IPV = Initial Production Vehicle

YNN-117: This vehicle was coil sprung all round and had a drive through diff on the intermediate axle. This was considered restrictive in terms of axle articulation and further the coil suspension did not lend itself to a load sharing arrangement on the rear axles which without could lead to overload on an axle in extreme conditions with potential resultant failure of chassis, suspension and/or axle. This resulted in the design you see on today's Perentie 6x6.

Once it was determined that its arrangement was not suitable for the intended role, the vehicle was stripped down and a new chassis fabricated in the ultimate Perentie manner. Coils were retained at the front and the rear got the overlapping semi elliptic springs. Much of the bodywork and running gear of the original was used except that it gained an Isuzu at the same time. What was left was sold off including the chassis.

The vehicle with the new fabricated chassis must have retained the Sandringhams identity as it was registered YNN-117 also and continued to be used until the first 110 based 6x6s were built. It was ultimately believed to have been reduced to components and scrapped.
