The Toyota Tundra third generation was the most comprehensive redesign in the Tundra''s 23-year history — not a refresh, but a new truck built on a new TNGA-F platform with a new engine family. The twin-turbocharged V6 replaced the 5.7-liter V8 that had defined the Tundra for a decade, and in hybrid form with Toyota''s i-FORCE MAX system, it produces 437 horsepower and 583 lb-ft of torque — more than the V8 it replaced, with meaningfully better fuel economy. The new composite bed floor was lighter and more impact-resistant than steel. The interior received the most significant upgrade in Tundra history, with a large touchscreen, heated and ventilated seats across multiple trims, and a material quality that finally made the Tundra competitive with the Ram 1500''s interior benchmark.
Tundra III owners chose Toyota for the reliability record that made the previous Tundra legendary — the documented longevity that makes Tundras valuable as used vehicles for 15 to 20 years after purchase. With the improved interior of the third generation, maintaining that interior''s quality over the long term is the appropriate ownership approach. These seven accessories address the Tundra III for the owner who intends to drive it for 200,000 miles.
1. LED Door Sills with Toyota Tundra Logo
The Tundra III''s CrewMax cab has one of the widest door openings in the full-size truck segment — wide enough that the sill is a prominent interior surface on every entry. Custom LED sill plates with the Tundra script or Toyota logo illuminate that surface at door opening. Available for both the standard cab and CrewMax configurations, stainless steel, LED wired to the door circuit. For the Platinum and Limited trim Tundra owners whose cabin specification already reflects a premium interior, the LED sill completes the entry experience at the point where driver and passenger first interact with the vehicle.
2. Heavy-Duty All-Weather Floor Liners — SuperCrew Specific
The Tundra III CrewMax has the largest rear floor area of any Toyota crew cab truck — significantly deeper than the Double Cab configuration. Custom-molded rubber liners for the specific cab configuration cover the full floor area with deep channels that handle the full range of truck use: wet boots, soil, construction debris, and outdoor equipment.
3. Bed Liner — Tundra-Specific Spray-On or Drop-In
The Tundra III''s new composite bed floor is more resistant to impact than the previous steel bed, but still benefits from liner protection for heavy cargo loading. A drop-in plastic bed liner or spray-on application protects the composite floor from the scratching and denting that regular cargo operations cause over time. The 5.5-foot or 6.5-foot bed configuration determines which liner fits.
4. Running Boards / Side Steps
The Tundra III''s ride height is higher than the second generation''s, particularly with the available TRD Off-Road suspension. Running boards that match the Tundra III exterior trim — chrome for Limited and Platinum, matte black for TRD Pro and Off-Road — reduce the entry step height and provide a stable entry platform for daily use.
5. Tonneau Cover — Tundra III Specific
The new composite bed on the Tundra III has a specific rail profile that requires Tundra III-specific tonneau covers. A retractable aluminum or folding cover protects bed cargo from weather, secures the cargo area, and improves fuel efficiency on the highway. For the Tundra used in professional or recreational contexts where bed security matters.
6. Seat Back Protectors
The Tundra III CrewMax rear seat is the most spacious Toyota truck interior ever — more rear legroom than the previous Tundra, with a flat floor and adult-capable rear seating. More rear seat use means more contact load on the front seat backs. Clear TPU seat back protectors handle this over the vehicle''s working life.
7. Wireless CarPlay Adapter
The Tundra III shipped with the Toyota Audio Multimedia system including wired CarPlay and Android Auto. A dongle adapter converts this to wireless — for a truck used for work where the driver connects their phone multiple times daily, wireless connectivity removes the cable management that interrupts productive use.
The Toyota Tundra III is a truck built for the long term — the same reliability philosophy that made the second generation last, applied to a substantially more capable and better-specified vehicle. These seven accessories maintain the Tundra III interior for the long ownership that Toyota Tundra owners are known for, protecting the materials and adding the functionality that the third generation''s improved specification enables.
