Leveling keys and some good 33-34" tires, whatever you can fit under it without a suspension lift would be the best compromise, IMO.
A new HD pickup will tow 8klbs no problem though with any off the shelf 4-6" lift kit and 35s and still feel more stable than a stock 1/2 ton.
I prefer a spring lift in back instead of blocks, but with a gasser, traction control and all that, I wouldn't worry as much about the torque and axle wrap of blocks in back compared to something older with no tq mgmt and gobs of diesel power.
Your fuel mileage and power will be su ckyer with big tires and lift, but the drivetrain is robust to handle it now and for years to come.
But yeah, it's mostly for show since it will still have the turning radius of a school bus.
That said, lifted Chevies look cool!
