2003 Tundra SR5 4x4 Box repair?

My bed has rusted through in two spots (where bolts go through to hold it down). Does anybody know a site that sells a “patch” that could be welded in place or another solution for this problem?

 

Unfortunately not. Toyota used to sell complete bed floors, but it a huge effort to drill/cut out and weld in the new floor. Used bed is the cheapest route. Some here experienced in welding have cut out and put in patches. Not the greatest looking, but with a bed liner cover over it, not very noticeable.

 

The big question is, if the bed is rotted thru, how's the frame?

Knowing the bodies of these trucks are far more resilient than the frames, and frame rot is in the "Top 3" killers of these trucks, alongside using non-OEM lower balljoints, and not changing the timing belt/water pump/tensioner/pulleys every 100k miles/10yrs, I'd want to know what the frame looks like in the big trouble spots (at the frame stiffeners, driver-side upturn under the brake MC, spare tire carrier and its tie-ins).

If the frame is rotten, patching a hole in the bed is either (A) an exercise in futility or (B) something a sleazebag does when trying to sell the truck to an unsuspecting victim who doesn't know about the frame issues.

What area of the country are you in? Replacement beds can be had for under $500 around me, one or two pop up per month. You need to match the bed to your cab type, and ensure the bed has appropriate fender flares for your truck.

 

My long bed had 5 collisions so I bought a junkyard bed. It cost me $880 in pretty good condition with spray in bedliner and included a perfect tailgate. Not very hard to replace and with the bed off it's a good time to clean the frame and spray Fluid Film in the nooks and crannies. Also was easier to replace the rear shocks.
