I messaged the Toyota Bend Oregon guy on his last vehicle and he said he added air bags to help.
??? look at how much torsion resistance the rear mount (doesn’t) have.
Per the description: " The truck frame is fully boxed in now from front to back , It also has gussets welded in as well . The front suspension has adjustable coil overs . The rear suspension has , old man emu heavy duty leaf springs , road active suspension helpers , Firestone air bags and upgraded shocks . "
Boxing the frame isn't easy if it's done right. I'd guess he had some issues with earlier models. And that rear suspension is pretty wild! Yes, it's going to be way over GVWR and you won't have much of a warranty (if any), but Truckhouse is like that too.
