pnichols - I was referring to threads like this one: Tiger vs. Earthroamer in which various members here dismissed Tigers as they did not have pivot subframes. My Malayan does, but I am not sure that that is really necessary for bad road use. My Tiger has a raised suspension, uprated shocks and Tires, etc., but its off road abilities are still limited by weight and weight distribution. And I would certainly agree about center of gravity. My goal was not to go rock crawling, but rather to survive miles and miles of bad, but passable roads. My background is Africa and South America.
That old Tiger vs. Earthroamer discussion link you provided went into great detail covering the dangers of an RV's coach area walls being rigidly attached to it's truck cab structure. Thanks.
Interestingly, earlier in this thread I published a photo of a 1969 all fiberglass bodied coach Chinook Class C we once owned that was built onto a GMC 3500 pickup truck chassis with it's bed of course removed but the cab left almost entirely intact. We could crawl from the cab back into the coach through the spot where the cab's rear window used to be. Chinook designed in a heavy waterproof flexible boot that was permanently attached to the rear cab's wall where it's window used to be and then permanently attached at the boot's other end onto an exact same size opening in the forward coach wall.
The above Chinook design physically isolated the coach structure from the cab structure under longitudinal frame twist situations, so it was superior to a couple of the Tiger models in this respect. However the coach was still exposed to any frame twisting right under where it was attached to the frame. This last concern is where the living area 3-point-triangle mounting system comes into play that expedition vehicles use.
I don't know why Tiger doesn't at least isolate the coach area from the cab area on it's standard CX and TX models to offer some degree of frame-twist protection to them. With only a soft connection between the the coach and cab, the CX and TX models could be then built onto radical Ford/Dodge/Chevy 4X4 one-ton pickups with oversize tires and be pretty close to a medium-poor-man's Earthroamer or real-poor-man's expedition vehicle - not counting system reliability issues out in the middle of nowhere in another part of the world, of course.
