I agree with this. I just purchased an 18' TT that weighs 3215 pounds dry weight and I'm towing it with a 2005 GMC Sierra 1500, regular cab, short bed, 5.3L (300hp), 3.23 gears and it's fine on flat ground or if the wind is not blowing.
I bought it 2 days ago and getting ready to move it to Terlingua, Texas and not looking forward to the trip down at all.
A 2005 4 speed (4L60E) and a 2016+ 8 speed(8L90) aren't at all comparable, other than final drive ratio they share nothing in common. The 3.42 is now the max trailering gear ratio, useful up to ~12,000lbs, it's equivalent to the older 4.10 transmissions. As I said up thread first is really short at 4.56 (4.56*3.42 > 2.48*4.10 in fact).
