Hitch Extension Options on OEM Hitches

Thanks everyone for your comments as I will again be able to make informed decisions with the information provided. This is especially true for the information provided by mkirsh and kerry4951. If the extension I need is 36 inches from the cross pin in the receiver and as you indicated mkirsh, if the normal hitch shaft (ball to pin) is approx. 9 inches, I will be reducing the design capacity by 36/9=4 times. Therefore if the design tongue load is 500lbs for a Class lll, I must keep my tongue load below 125lbs or switch to a torklift or reese hitch. I am still trying to confirm which class of hitch comes OEM with GMC 3500. Kerry4951 I sure do agree on your comment about the truck advertising pictures. cheers everyone
