yep. some of it I can honestly take credit for. most of it is engineered into these trucks from the beginning. A smooth belly, stout chassis components, ease of access for changing spark plugs, installing headers, and dropping oil pan, distributor in the front, and I can reach everything under the hood without a step ladder...all this has spoiled me. I hate working on all the 4X4 trucks from the same era built by the Big 3. Ever tried adding headers to a 1970s Ford truck? or Dodge? or Chevy? Lotsa work. Drawbacks are : not as popular so after market parts can be pricier than Chevy parts. also they are usually defective out of the box...or just the wrong part. And due to 4WD being engineered in from the beginning, it is a smaller, more efficient chassis, without 4-inch lift blocks in all the leaf-spring packs...so these ride lower, therefor have Iess lateral body roll when cornering, but sadly get high-centered easier on berms and snow drifts due to less ground clearance. But they easilly fit 32X11 (or 33x12 tires with good stock springs. In the late 1990's I had 305/70 - 16 (33x12) Goodyear MT directionals - Humvee tread, but not size) on centered 16×8 wheels. but the 33s rubbed the outer lugs on the inner lip of the Front Fender Flare with the suspension fully compressed and steering fully locked. Im out of words. I dont blame you if you're like: TL, DR !
