jefe,
Those Cooper tires have been phenomenal on both my converted Dodge 250 van years ago, and now on my current 4X4 Z71 GMC. I'm on my 2nd set in at least 12 years on the Z71 - they wear like iron. The 1st pickup set went at least 10 years - no sidewall cracking, either, sitting around in the CA sun all those years. I was running over-stock diameter LT285's on it for the 1st set of Coopers, as I needed the diameter for higher clearance on rough roads doing volunteer work in the backcountry of Henry Coe SP. I did this with the good old GMC 350 CI gasser grunting along, some of the time of course in low range when having to twist the big tires up steep grades. For what it's worth, Rancho sent me at no cost a new full set of their 9K shocks after my first 5K set failed prematurely on the GMC. I can't figure out what setting to use on 9K's though ... the GMC rides like a bucking bronco when empty regardless of which number I use.
If I'm reading your signature correct .... you're running only a 3.54:1 differential. Even though your mill is a CTD, couldn't your long climbs at high altitude benefit from a bit better pulling ratio - especially after adding those way larger than stock diameter tires?
Keep up the great Dream Trip postings! :)
