Yes Ben I have. and I suspected the accuracy of those claims when Dave made them a year or so ago.
I don't really understand the fitment of drum brakes though, unless it is to insure at least some degree of braking performance when reversing back down steep gradients in the event of engine failure causing loss of vacuum assist?
Does the 4x4 rear suspension feature multiple links, or travel limiting, antisquat inducing radius arms like the older G wagons?
You don't happen to have a photo depicting the 6x6 thru drive for the rearmost axle?
Bill.
