2015 GMC Sierra 1500 vs 2015 Toyota Tundra
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 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.
VS
2015 Toyota
Tundra
8/10
Buy it for the 5.7L iForce V8 and the fact it'll outlive you, not for fuel economy or tech.
Milo scores the 2015 Toyota Tundra higher — 8/10 against 6/10.

If you buy one, buy this one
✅ 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.
✅ 2015 Toyota Tundra
2015 Tundra CrewMax (Double Cab or CrewMax) SR5 or Limited with the 5.7L V8 and factory tow package — the sweet spot of reliability, space, and resale without paying 1794/Platinum premiums for leather you don't need.
