I been reading about this issue but in old school world heavy 1/2 ton rig shouldn't go over 12,000 lbs GVCW ( truck and trailer ) it was just a rule of thumb for years. And with a 24 ft travel trailer hitting 6250 and 1500 lbs of gear water etc. 7750 lbs and if rig at 5700 lbs 13,450 lbs add people and fuel your over 14,000 lbs . Its numbers RV people been fighting for years. I see 30-35 ft trailers guys pulling with 1/2 tons pretty much all of them can tell you a transmission story. Depending on how many miles they pull them.
This just what I have learned for years .. Hope the info helps someone..
These aren't our father's half-tons anymore. I drove an '81 GMC Sierra all through high school with a 250 straight 6 sporting 115 hp and rear drum brakes, yet my dad towed our camper with it before I got it. Today's half-tons are in a whole 'nuther class. Even before modifications we're talking 400+ hp/tq for the GMT900 Yukon XL Denali's, with running gear, cooling systems and brakes to match, with 14,000+ lbs GCWR.
