Strong towing numbers and a diesel that actually delivers 28-29 mpg highway, but you're gambling on two expensive failures: the 8-speed automatic shudders and slips toward a $6,000 rebuild, and the AFM lifter system collapses into a ticking mess that demands cam replacement. Transmissions have failed at 83k miles, lifters strike seemingly at random, some trucks cruise past 200k, others need major work before 100k. The GMT800 generation (1999-2006) earned its reputation as bulletproof; the current truck tows competently but trails Ram and Ford in cabin refinement, with materials that don't match the sticker. Budget for an AFM delete if buying new, or find a clean GMT800 and avoid the lottery entirely. Skip this if you want modern interior quality or can't stomach four-figure repair risk.
GM's upscale twin to the Silverado wins on looks, even Ford loyalists admit it's the best-looking truck you can buy, but the engine choice matters more than the badge. The 5.3L V8 is the workhorse: proven across 200k-mile police fleets, boring in the best way. The 3.0L diesel hits 28 mpg when it works, but some batches grenaded early, and the 6.2L left 2020-2022 owners stranded with catastrophic failures. The infotainment skips and mutes itself on 2022+ trucks, a known bug GM has ignored for years. Pricing has crept into luxury territory, lawyers and soccer moms, not the working crowd. Buy a pre-2020 model for proven reliability, or spec a new one with the 5.3L and a strong warranty. Skip the 6.2L on anything 2020-2022, and roll the dice on the diesel only if fuel economy justifies the risk. It'll tow your world and turn heads, as long as you pick the right engine and forgive the screen's morning mood.
