2013 Toyota 4Runner towing
However, we also see this issue from the automakers' perspective. Pickup trucks are hugely profitable, and even though we know many great, thoughtful people who work at car companies, given the cash that's at stake it seems unlikely that any of them (Toyota excepted) would put themselves at a disadvantage by publishing lower tow-ratings simply because it's good for consumers. We're sometimes naive, but we weren't born yesterday.
For now, we're in a transitional phase as automakers switch over to the new standards. Until all automakers begin using J2807 -- which could take several years -- customers will have to continue being diligent in showrooms.
