    John, I have read, followed and book marked your write up when you wrote it. GREAT information. Thank you. I am just concerned with going to low (past level) in the rear of the truck with the trailer on, but also hate to raise the trailer any (it is tall enough!). Man, Ford made these new trucks TALL!. Sorry for the side track. Now back to your regularly schedule interrupt and the original posters questions.

    Hi Chris
    I have a 2016 F350 Platinum single rear wheels with a GVWR of 11,500 as per door sticker. Are you saying that my GVWR is actually higher if I use the axle ratings. If so my rear axle is rated at 7200 and my front axle is rated at 6000. Does this mean my GVWR is 13,200?
    Thanks

    GVWR never changes - it is what you are taxed on. If you live in certain states where the registration cost is based on GVWR, most manufacturers offer an optional (lower) GVWR. Same truck, just a lower GVWR and lower cost to register. Unless you are a commercial operator, exceeding the GVWR will damage only your conscience.

    The individual axle weights should not be exceeded. Generally, axle weights are the lower of tire, axle or suspension ratings.

    Here is some info on using Axle Weights instead of GVWR.

    By Bob Raybuck
Director of Technical Services
NTEA
    Often, GVWR and gross vehicle weight (GVW) are thought to be the same, but they are not. A truck’s GVWR is the maximum weight rating established by the chassis manufacturer. GVW is the total weight of the truck and payload at a point in time.

    There’s a common misconception that a truck’s GVWR is determined by adding gross axle weight ratings (GAWRs) together for all axles. Although this was a common way of calculating GVWR many years ago, it’s no longer an accurate method. The chassis manufacturer task of establishing a vehicle GVWR is much more difficult today due to advancement of safety system standards and how vehicles meet these requirements. This is why many trucks have a GVWR much lower than the combined axle ratings. It is not uncommon for a truck with a GVWR of 19,500 pounds to have a front axle rated at 7,500 pounds and a rear axle rated at 14,700 pounds. Safety standards that apply to braking, vehicle stability, and chassis manufacturer internal standards for durability, dynamic stability and handling can restrict GVWR even though the sum of the axle ratings exceeds 22,000 pounds. In this instance, the OEM set the GVWR at 19,500 pounds based on test results and vehicle dynamic performance to ensure a safe, reliable truck.

    This statement shows up in Manufactures towing guides and Manufactures Owner Manual.

    “5th-Wheel Towing Notes:
    This information also applies to models with pickup box delete option (66D). Trailer kingpin load weight should be 15% of total loaded trailer weight. Make sure that the vehicle payload (reduced by option weight) will accommodate trailer kingpin load weight and the weight of passengers and cargo added to the towing vehicle. The addition of trailer kingpin load weight, and the weight of passengers and cargo, must not cause vehicle weights to exceed the rear GAWR (Gross Axle Weight Rating) or GVWR (Gross Vehicle Weight Rating). These ratings can be found on the vehicle’s Safety Compliance Certification LabeL

    If you watch how you load and load light you get away with low option 1-ton SRW Diesel but mine I would overload my GVWR GAWR and Trie Ratings if loaded to the 15,000 GVWR of the 310GK. Look this over and these are CAT scale.

    It sets about 1 high in the front but only has 5 inches of clearance between the 5er and the trucks bed rails.

    Howittro - The above replies pretty much cover GVWR and axle ratings. The GVWR is whatever the manufacture printed on your official door sticker and only the manufacture can change it (which they never will). My personal take (nothing official) is the GVWR is a **general** representation of a trucks capability. It is very handy to compare different classes for trucks (1/2 ton vs 3/4 ton vs 1 ton SRW vs 1 ton DRW). It is also used for legal purposes and may effect your taxes/license fees. Violating it by a little **may** have legal consequences (ticket or ??) if you are ever checked. The axle ratings, as SouthTX said, the axle weight ratings are the least of many separate components (tires, wheels, axles, springs frame, etc). While engineers design in margin on each part, exceeding the axle weight rating is **in my opinion** is risky as you are cutting into YOUR safety margin. You should do what YOU are comfortable with.

    We had this explained to use at FMCA seminar by a retired Ford Engineer. GVWR is Chassis/Frame Rating independent of the axles and not overall general rating. He provided us the link to Bob Raybuck
Director of Technical Services
 NTEA that I quoted above. The Frame is part of the GVWR assigned to the Chassis and the axles have their own rating. Exceeding the GVWR your exceeding the Chassis and Frame ratings but most likely not the axle ratings. That is why tow guides and trucks manual has the warning not to exceed either the GVWR or the GAWR. GMC even put warning that exceeding the GVWR can cause "Unusual suspension behavior, making the vehicle hard to control" and "Brakes unable to stop the truck or SUV in a timely manner".

    Even the manufacturer cann't change the sticker. They would have to call in the agency that does the certifying and pay them to re-certify them. At least this is what I was told by GD.

    I want to play off the structure Dennis used above as I reviewed this thread when deciding on my truck. I went with a standard bed SRW because a) All my local experts said it would work for our needs, and b) The spousal approval factor of getting something that will fit in our garage and make a more friendly DD. Prior to her calling in the experts, I was convinced I needed a DRW.

    We've already towed the 310 GK over 700 miles, twice going over 10,000' altitude. The rig works so much better than our SUV and travel trailer combo we're moving up from. But I could also guess what a DRW would mean for increased stability and payload margin.

    12,222 Factory UVW 14,240 Scale Weight - Gear and water 1,838

    Some of my notes:
    I rushed through the weighing because the president of the division was helping me, not the shop guy I was expecting. There were some inconsistencies I'd like to address when I go back in a couple of months.
    Front axles lost 120 lbs because of the pin weight being slightly behind the rear axle.
    I had the freshwater tank more than 2/3 full. Truck was nearly full of fuel and DEF.
    Our 310 GK has the generator prep, but not the Onan yet. No washer either.
    Depending on the conservative or generous weights I look at from today, I have 280-440 lbs of payload to work with.

    The offset ball for the B&W gives me enough level-ground clearance for tight backing, but I'll still be very careful.
