It still amazes me that people think a 5-6k lb half ton towing 10-11k lbs is absurd, but a 8-9k one ton towing 30+k lbs is perfectly acceptable. This is one reason why I think we need to get rid of terms like half tons and one tons because people place there expectations on what a half ton should tow in their mind rather than looking at the actual capabilities of the truck. To them it is perfectly fine that HD/SD trucks have increased tow ratings to absurd amounts over the years, but the half ton will always be good for towing less than 7k no matter how much they have been upgraded over the years.
In a nutshell, this ^.
If the OP doesn't like the handling of a 7500lb trailer behind that truck, then either it's not setup right, or you likely won't be happy with a newer 1/2 ton either.
The main things that determine stability of the truck while towing are tires and spring rate. Neither of which are heavier on new trucks and both of which are easily upgrade able a couple ways. Add springs and tires to your 1/2 ton or buy a 3/4 ton. Either way your paying for the upgrade. You're not going to gain much of any power going to a 3/4 ton gasser from your current Denali 1500.
This is a classic example of either lack of towing experience, too discerning of expectations, not setup right or believing the hype on rvnet.
And weight is only one of the factors that determines how something pulls. And the difference between 7500 and 8500 lbs isn't much. Wind resistance, tongue weight, how the wdh is setup (in your case), how the truck is prepped, how much weight behind the rear axle of the trailer, axle placement, trailer axle capacity etc etc all factor in.
Yes "over trucking" the setup reduces or negates some of those concerns, but many of them either can't be changed or will present the same with a bigger truck.
Not trying to talk you out of a bigger truck. Yes it is an upgrade and it will (arguably) negate the need for a wdh which simplifies the equation, but if the trailer wiggles behind a 1/2 ton it will still wiggle behind a bigger truck. And you'll feel it.
Back to the lack of experience part, it's the middle of winter, so just observe for a while, all the different trailers you see behind differnet trucks on a daily basis and you'll see that your truck is not out classed for the trailer you have.
