First of all, David, nice looking rig man.
Secondly, I have to push back a little on this, as your Land Cruiser brother. When I was in Sooke's place a year ago, I kept hearing this "it works fine but if one component fails' argument and the "and then your stuck on a trail with a suspension that doesn't work" bit. It seems to be ubiquitously passed around in any forum that mentions AHC, but I've never understood the logic...
Yes, a part of the AHC system could fail, and you have a trail problem to solve.
But could one not also say that about many parts on your engine and your engine system as well? So do we "delete engines?"
Sorry, I had to get that in there for all the AHC lovers out there....
