2015 Ford F-150 vs 2015 GMC Sierra 1500
Two full-size trucks, compared on what actually matters when you're buying used:
what breaks, when it breaks, and what it costs you.
2015 Ford
F-150
7/10
America's best-selling truck reinvented in aluminum: light, capable, and cheap to run — but 2015 was year one, and the 3.5 EcoBoost and 6R80 transmission both have baggage.
VS
2015 GMC
Sierra 1500
6/10
Buy the 5.3L V8 with the 6L80 auto for parts-bin simplicity, but budget for a transmission rebuild by 150k and get the vacuum brake booster recall verified before you sign anything.
Milo scores the 2015 Ford F-150 higher — 7/10 against 6/10.

If you buy one, buy this one
✅ 2015 Ford F-150
2015 F-150 XLT SuperCrew 4x4 with the 2.7L EcoBoost and Max Tow (302A package with 53B). Aluminum bed, modern power, better MPG than any V8, no 3.5 timing-chain risk, no 5.0 phaser risk. Second choice: 5.0 V8 XLT with the same trim — for the sound and simplicity, if you don't need MPG.
✅ 2015 GMC Sierra 1500
A 2015 Sierra SLE or SLT crew cab with the 5.3L V8, 6L80 transmission, and complete recall/service records — ideally one that's had regular full transmission fluid services, not just a top-off.
