Thank you for the reply.
My van is probably a bit heavier. It started as 1.3t but with extras and water I suspect in is still well under 2t.
From what you say above my situation does seem strange then.
When slowing down to a stop you probably would not use 6v and my max setting would be within the boundaries. So having it set higher than my 3.6v or even using boost should not make any difference in the slowing to stop scenario but it does. I started at 6 and went up to the max even but that was worse.
However, also from what you say, my setting of 3.6v should be OK. I would be a bit more comfortable if it was higher but then it becomes jerky when stopping. may be some more driving will help.
