A mate of mine has one,fully kitted out,been all over the countryside in the last few years,not a single issue.
His has BP-51,ARB setup,and it rides extremely well,weighs 3.3T on the scales at the dump,empty,full of fuel and water,just driver.He has also had it fully sound proofed,doors,floor,everywhere,but its still noisy,more wind noise than anything.I have the BP's on the LC200,and love them as well.
It has a turning circle similar to a Puma,so can be an effort to park and also turn on tracks at times.
He has just recently had the wider axle done,and said there isnt a lot of difference,actually probably not worth the $.
For dual batteries,go lithium if you can afford it,they are so much better.
DCS do under bonnet,have done for quite a few years now.They actually have 130A lithiums for under bonnet use in the 200,but i dont know if they will fit under the 79 bonnet easily.
Once my batteries are shagged,i will go Lithium.
