I know this is an old thread, but I suspect it comes up on a lot of searches. For anyone on the fence about whether to get this hitch, or try to modify and reuse your OEM hitch, let me tell you now, go ahead and order the Demello hitch when you get your bumper. I thought I'd try to save some money and try to modify the factory hitch, especially since the Demello hitch had gone up to $250 when I ordered my bumper, not to mention the Toyota hitch is certified to tow. But after installing the bumper, I realized that to even have a chance of working, the factory hitch would require major cutting and grinding, so much so that the strucrural integrity would likely be
compromsed. Even then, I'm not sure it could be made to fit. If anyone has done it and made it work, please post pics. Anyway, I ordered the Demello hitch, paid the shipping I could have saved if I had just ordered it as the same time as the bumper, and waited. Several months and emails later, it finally arrived. It comes with heavy duty grade 8 bolts, and seems like it will hold up. I haven't done any long trips pulling my 3000+ pound camper yet, but I did pull it about 10-15 miles and it did fine. I plan to pull it more, and if I ever have any problems, I'll be sure to post here. One minor gripe, the hitch fits farther back than in the OEM and it's kind of a pain to put the pin in receiver. But I guess that's the tradeoff for getting I high clearance bumper. Anyway, if you're on the fence about getting the hitch, just go ahead and order it when you order your Demello bumper.
