Lots of great info
Thank you much certainly much to consider.
I am still trying to figure out exactly the week point of these hitches.
I have not been able to locate a pic of a failure of the factory hitch. But that would be appreciated.
The failures I have seen on the GM hitched seem to be related to the actual receiver ripping away from the crossmember. If that is the week point, that can be easily fixed by gusseting or plating.
I hear your points on cutting the reinforcing channel. Seems very sensible. I am however stumped as to why the frame in that area has the unused weldnuts in the frame. My assumption was that it was because the GMT900 Suburbans share a frame with the trucks which use those nuts for their hitch.
And so the questions continue.
I did not that there are hitches that, unlike the Curt, seem to be more knife edge in that area and may be able to clear. The DrawTite 41930, which is rated to 1200lb tounge in clearly more robust than stock.
Still need to do some height measurements and understand if being lower with the hitch would help. I tow both a travel trailer and a car hauler.
Thanks all for the input. The best thing I can say is that there does not seem to be a rash of these hitches failing on the 900 series Suburbans, so I am not super concerned. But I will address it.
