OK....this is good information, although a little foreign to me! Our Suburban is a 2007, don't know the rest of the info. My husband drives it, so when it gets home, I will look in the owner's manual for the information above. Just glad I am thinking about this BEFORE buying a trailer. I did think that all Suburbans were basically alike. And, every sales person we have talked to has asked about our tow vehicle. We tell them we have a Suburban, and they just say "Oh, then you will be able to tow anything I would sell you with no problem." I guess this is not true!!!
