There is a recall on Tundra tailgates.

F150/Titan have fully boxed frames. Tundra boxed as far back as trans, then two different sizes of C channel to rear crossmember.*

F150/Titan available with power adjustable pedals, Tundra is not. F150 (some) and Tundra have telescoping steering wheels.

F150's assembled in Dearborn, Titan's in Corinth MS, Tundra's in San Antonio TX.

Dunno anything about Ram's except its hemi is a semi-hemi. Don't care about fugly Chevy's (front end looks like it was born on its nose) & GMC's with their 'ancient technology' "cam in block" V8's.

Chevy TV commercial with Howie Long as spokesperson road tested F150 over railroad ties to exhibit frame/bed flex.

F150 TV commercial with Mike Rowe as spokesperson road tested Chevy over railroad ties to exhibit frame/bed flex.

2007 Chevy introduction on Speed Channel: Howie said look at our innovative bed cargo management system and wide opening rear doors (on extended cabs).

Titan had both in 2004. Chevy bed management rails are thin strips of aluminum, while Titan's are heavy cast aluminum.

* Toyota at 2007 LA Auto Show had a Tundra rolling chassis mounted at a 45 degree angle. I took pics, sent them to (I think) Steve Bricks who posted them in the SoCal Chapter.
