New Opticruise is a lot better than old opticruise,
When i drove one in an R series, (Only around the block, but a big block) I was very impressed, 100% over the old version,
theghostofcain, if you drove an R series then it was new if it was a 4 series its old,
It is still not perfect, i hear a lot of moans about it when pulling off, you get going then it changes and during the change you lose some momentum so it does not pick up as easy,
You have the clutch for slow speeds, ie in yards, backing on to bays etc,
when on the road its fully auto, change up and down on its own, you can also manual overide it if you want a different gear,
Its a bit like marmite, you either love it or hate it,
I would advise you to have a demonstrator for a few days to see if you like, I can’t think of anything worse than to order a truck only for you to hate it because you never chose the right box, Have a go in both and make you decisions,
Only you know if its right for you or not
I believe flatbedman on here somewhere has an R series with opticruise,
Hope this helps
