General Overview
The 2003–2009 models represent the fourth-generation 4Runner (chassis code N210), built on a ladder-frame chassis with independent front suspension and a 4-link rear coil axle. The 2010–2014 models continued as the early fifth-generation (N280) design, still featuring the same rugged underpinnings. Trim levels across these years included SR5, Sport (2003–2005), Limited, Trail (from 2014), and off-road-focused TRD packages. carsdirect.com+6toyoland.com+6motortrend.com+6en.wikipedia.org+1de.wikipedia.org+1

Real-World Owner Insights
- Many users tow confidently up to 5,000 lb with V6 models, especially when equipped with weight-distribution hitches and upgraded cooling. V8 models are capable of towing larger loads (up to 7,300 lb). toyoland.com
- Payload often exceeds factory ratings in non-off-road trims; again, platform limitations may reduce usable payload by several hundred pounds.
Summary
Between 2003 and 2014, the Toyota 4Runner evolved from a rugged V6 platform to incorporate V8 options with improved power and towing. The V6-powered 4Runners tow 5,000 lb comfortably; the V8 versions tow up to 7,300 lb. Payload capability is strong across trims. As a mid-size, body-on-frame SUV, the 4Runner delivers exceptional durability, off-road systems, and versatile SUV comfort.
