Pages 1-50 good info
fifthwheelst.com/documents/gmc/2004_gmc_sierra_owners.pdf2004 GMC Sierra 3500MAX Tow Rating is derived using a BASE Model with 150# driver and 20# cargo
Actual weight of truck loaded up camp ready (passengers, stuff in truck, stuff in truck bed, hitch and pin weight) deducted from GCVWR is what the actual max tow is....provided you do not exceed trucks RAWR/Rear Tire Max Load Ratings
Wet pin weight is at minimum 20% of actual trailer weight.
Example:
My 07 3500 SRW is rated at MAX Tow of 16,300 with GCVWR 23K
I tow a 14K 5vr (Scaled weight 13,873#) which puts truck right at RAWR, under Rear Tire Max Load Rating and under GCVW
Any heavier 5vr and I would exceed RAWR
My GCVWR 23,000 minus GVWR 7980 ==== max tow 15020 but I am AT RAWR with just under 14K 5vr.
