Chevrolet Silverado

Looking at either the 2026 Silverado 1500 LT with the 6.2L V8 or the F-150 XLT with the 3.5L EcoBoost for towing our new travel trailer (7,200 lbs loaded). Both seem capable on paper but I want real owner experiences. How's the stability? Fuel economy while towing? Any issues with transmission temps...
