Pulling over the tow rating


Recommended Posts

Posted

We've got a 96 CC dually,454 auto,4:10 with a tow rating of 10,500. The 5th wheels were looking at come in UVW at 9,900 to 10,500. Add 1000 lbs of gear and

were up to 11,500, 1000 over. We pull about 4 weeks out of the year. So who's pulling over their rating.

how did you get to the 10500# tow rating?

 

the only rating i use is the gcvwr - the actual weight of the truck loaded and ready to go = tow rating.

 

so my 03 gmc has a gcvwr of 16k# - 6000# truck weight = 10000# tow rating...

 

i would never recomend going over the gcvwr. i would also plan for more than 1000# of stuff in that trailer. water, propane, food, clothes, gear.... it all adds up quick.

 

now will the truck actually do it... most likely, but for how long till you find the weak link in the set up. i believe your truck has the same tranny as mine, which may be the reason for the lower rating than the newer duallies. all the newer trucks with the higher ratings have the allison tranny.

I see guys towing over weight all the time. I just saw a guy the other day who had a F350 duallie pulling a 22000 GVW trailer with a 16000 lb tractor backhoe on it. He had all the DOT stickers and he said he was perfectly legal. I would think that truck could pull 10500 easily being a 5th wheel. Although I don't know the specs on that truck for sure.

 

Mine is rated around 15K for a 5th wheel.

Most often it isn't the matter of pulling but stopping that is the problem. I used to pull a construction king 35ft with beavertail and a case580 backhoe with my early 90's dodge cummins. It would pull it ok but had very little control if the trailer started to weave at all. It got kind of scary at times and trying to stop in city traffic was difficult to say the least. Thats when i decided to go with a top kick medium duty truck. The extra beef of the truck and brakes made a world of difference.

It's not legal... but being that you have a dually, you'll probably be OK. I don't recommend anything that is illegal, but I'm not saying that even I haven't been over my limit in the past.

 

For years I towed a 30' Coachman travel trailer with a 5-bolt G20 Conversion Van. I always played it safe and had a good brake controller for the trailer... If the brakes for the trailer failed, then I would have been up a creek without a paddle.

 

I've seen worse rigs going down the road... Like a Durango pulling a 21' cabin cruiser speed boat!!!!

I heard it on the internet so it may be true or false. Your insurance company may or may not cover you if you are overweight and in a wreck. Might check it out to be sure.

I've heard the same from heavy equipment dealers.

    • It is possible to add your own 12v outlet to your truck.  Check out this video:   I verified via GM Upfitters that pin 31 is the same on the 1500 trucks.  The wire is GM part number 84779405.   You can get the GM 12v outlet from Amazon  https://www.amazon.com/Genuine-Accessory-Receptacle-25774623-13549530/dp/B0F1H9YRGF EWAY 12 Volt Power Adapter for GM   https://www.amazon.com/EWAY-Chevrolet-Silverado-Cigarette-Ignition/dp/B0915RRW6Q/ref=sr_1_1?   I just haven't figured out a good place to put the 12v outlet in my truck.   Some people are getting USB-C to 12V adapters  https://www.amazon.com/WYMECT-Cigarette-Lighter-Socket-Adapter/dp/B0F87WNQKB/ref=sr_1_1_sspa? Not sure if they provide the correct amperage that a device like a tire inflator would need.  
    • Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.
    • This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.  
    • 2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.  
    • Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
