Most seem to have substantial beef added... definitely in the crossmembers, some elsewhere, too. Mine is also braced back along the bottom of the frame a ways, then tied into the engine mounts and new shock towers, with plating along the inside of the frame back to where it goes to taller section. With Isuzu's stout frame (DANG, that thing is heavy!), it has held up well.... even when it was 'wheeled instead of parked. <img src="/forums/images/graemlins/rolleyes.gif" alt="" />

I'm not sure the Isuzu frame isn't sufficiently stout as-is, but I am sure that more metal can't hurt I have seen Toyota frames break near the front spring hangar, but the First-Gen Amigo/Rodeo frame has more section height forward of the firewall and thicker wall rails, as well.
