The sag is easily handled with air bags, I have a freind who uses a bicycle pump to air up her Dodge diesel when towing equipment. I never realized how cheap or simple it could be.
Having 40 years of lifting 4x4s behind me.... I'd say learn to live with the reliability and capability Toyota engineers built in. Stay stock. After 33s and 35s and 4 lifts on various Wranglers my TJR is now back to a fully stock suspension and driveline and I love the reliability.
Lifting, bigger rubber creates a gas mileage creep, we notice it but since it happens over time we kind of justify it with... "but my truck is more capable"... not... sorry but most often lifts, bigger tires just make a truck more vulnerable to breakage and unreliable.... plus a gas hog.
Getting rid of 33x10.50s and fitting 7.50R16s I went from 17mpg to 22mpg.... no other changes, pizza cutter tires, added 95 miles to the range of my TJR. I now have zero need to carry a Jerry Can. And I have yet to find a spot bigger tires would be an advantage.
