I did the spring lift thing and I got the heights I was after and it all works well now however it took a bit of getting the death wobbles out of it.
I did new shocks, new bushes in the idler, caster wedges, stiffer 2nd leaf, Sway lock bar on extenxded shackles, and then eventually found out what causes it and fixed it. (there may be an aftermarket bolt on product in this if a manufacturer wants to contact me) Its great now and has done a few trips.
I have also fitted a front lokka and that makes a real difference. Its mostly going as I hoped and is seriously unstopable. the only issue left is to solve the overheating.
Low first and 2nd in steep country on a hot day and it boiled.. Refilled it and turned the heater on and that was enough to keep it from boiling but then I had trouble not boiling and needed lots of fluid.
I am researching the air flow over the bonnet and may end up putting louvres in the bonnet to let the hot air out.

the km are only slowly going on and its nearly up to 148,000.
