How much can my truck tow? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Edmond · 12-29-2002, 06:24 PM

I hope you guys can help me with this...
I need to know how much my Truck can tow, officially.
I searched the Restopacks, but didn't find any info on this.
Did GM give any advise on how much the Truck can tow? If so, were can I find this info?
I need this for my registration papers, if I want to make it legal
to tow more than 1600 lbf.
If anyone can help me with an official document from GM with this kind of info, I can go to the state inspection and get it on my registration papers.
Please help me...

I need it for a 1971 C/20 Longhorn.

Thanks in advance

Cya,
Edmond

i would think its more with the rating on your bumper and hitch set up. i know my long horn has a strong bumper but if i was going to pull something really heavy id buy one of the new hitches. they have offical ratings

Hey Edmond, how was Santa to you ?
I am going to go out on a limb here and make a guess as to your question. My owners manual states that when towing a trailer, it is to be balanced at 10% tongue weight.
The max a vehicle could then handle would be the rated GVW- the tongue weight.
Say your 71 C20 is 7000 GVW ( not accurate but just say). If the truck weight is 5000 and you and passengers and gear is 1000, that leaves 1000 difference to meet GVW. That second 1000 is 10% of trailer so it would be 10,000. The deciding factor then would be the capacity of your hitch for the for the tounge carying weight and load pulling weight.
Make sense?
Look on page 8 of your resto book and pages 2-3 of the owners and drivers manual for more accurate info on front and rear GVW loading.

Don't know what it is rated for but I have towed a 23 foot travel trailer behind my 68 Chevy without problems. I have a class III hitch and an electric brake controller mounted on the truck. I believe the trailer is over 4000 pounds.

Edmond · 12-31-2002, 06:16 AM

Thanks for the info guys!

Kevin, thank you for the info, but unfortunally that is not enough.
They must have an official document from GM stating it can tow a surtain amount of weight. So for now I'm still doing it the illigal way,
but that doesn't feel right. If I do succeed, I will let you know....

To be continued

Cya,
Edmond

PS
Have a great New Year everyone!!

Must be really different there.
Here I have a half ton truck. We all know it is not a 1000 lb. vehicle. It has a 10,000 lb. Road Warrior bumper which is frame mounted and considered a load distributing bumper. Not a load bearing bumper.
I run a 2" ball, pull a 10,000 lb. trailer, (two 5,000# axles), and a 6500 lb. 843 Bobcat.
I have the truck tagged with 12,000 lb. BL plates.
As long as my plates cover my combined total weights, the hitch is rated for the tongue weight and the pull weight, I am OK. If I add a bucket to the trailer, a fuel tank and tracks I would go to 18,000 lb plates or up to a 3/4 ton truck. You have a 3/4 ton. Should be no problem and would not be here.
I will do some looking around. I would think that an original sales brochure would show that info.
* Just looked at my 1972 sales brochure. Next to the last page says "Required equiptment", "for trailering specifications, ask for the 1972 Trailering Guide."
There it is, post and see if anyone has that publication. If I find it for 71, I will scan it to you.

Hi Kevin,

Well I have both the 71 and 72 sales brochures, but they are Canadian editions, and I could not find any info regarding towing.
Perhaps the sales brochure for the US is different?

Now for the other publication, I need the help from you guys again.
If any of you have the publication NU2-72 is revering too, please help me out by scanning the publication and send it to me by email if you can. Or post them on this board.
This is the 1972 Trailering Guide or (even better) the one for 1971.

Thanks in advance.

Cya,
Edmond

Ive checked in the Dealers Data Manuals and have not been able to find anything about towing weight limits. Sorry

JoetheMobster · 01-02-2003, 03:09 PM

When you hook up the load, push the gas, and the truck won't move, you have too much!!!

Stopping you say? No problem, keep your seatbelt off, and the door unlocked, ready to bail.

Sorry, just kidding around.

JoetheMobster · 01-02-2003, 03:11 PM

Don't go too far though, I can tell you that!

Edmond · 01-04-2003, 05:05 AM
