Might be towing one home!
Sorry if this question is a repeat, I've searched, but couldn't find anything...
I'm curious if anybody knows an approximate weight of a 3/4 ton 67-72 longbox 4X4 with a 350 V8. Also, if anyone has experience towing this rig on a 7,000lb capacity tandem axle car-hauler trailer, please chime in! Thanks ![]() |

Re: Might be towing one home!
It probably weighs a little over 5000 lbs. What vehicle are you towing it with? How long is your trailer?

Re: Might be towing one home!
Curb weight is about 4500 plus another 100 for A/C. This covers most small options including an auto. trans..

Re: Might be towing one home!
My 69 C20 with a 350 was 5300 at the scales last month, no AC and a half tank of gas. This is after I converted to a C10 and got rid of the big Dana 60 rear and put a ford 9 in it. I say yours is closer to 5500.

That sounds really heavy. I'm going on published GM curb weight and have in the past been very close adjusting for installed options at their published weights. Your truck should be about 900 pounds lighter. Have to wonder about that scale. Here is a link were we were debating the weight of a Longhorn that didn't end up being weighed but was listed at 4960 which was probably with the steel cap as well. http://67-72chevytrucks.com/vboard/s...d.php?t=528006

Re: Might be towing one home!
A friend of mine and I went to buy a load of gravel in his 4X4 long bed, the truck with both of us in the cab weighed 5200lbs. There was no AC or anything extra on the truck. You should be safe guessing it at around 5000 give or take a cheese burger or two!

Re: Might be towing one home!
My Cummins powered K20 burb scaled at 6000 lbs, so you should be a bit under that.
Just remember that the 7000 lbs has to be calculated with the weight of the trailer and vehicle on it, but not the tongue weight the truck supports. My 7k car hauler weighs 1900lbs empty.

Re: Might be towing one home!
I don't know the exact weight, but I can tell you it's heavy. I towed one with a one ton, and it was still trying to push the tow vehicle around. Of course, we've got some pretty serious grades around here, but I'd still be careful.

Re: Might be towing one home!
Thanks for the thoughts thus far guys.
As I figured, it sounds like the truck on my trailer will be 'right at capacity', which is where I guessed it would be. I've got decent trailer brakes, and the tow vehicle is a late-model Suburban with weight equilizing hitch and rear airbags. Our local countryside is relatively flat. As long as we go slow and take our time, it should work. |

Nice looking truck. I'm glad you posted those pictures, I never thought about putting a truck on the trailer backwards, but it makes sense to balance things out better. |

Most important thing is have enough tongue weight, and check trailer tires. And don't use one of those little u haul jobs that barely fit a lwb and sway over 55mph. Spend 150 and rent a bobcat trailer if you have to. The longhorn we pulled all the way from Washington state to MN with same truck and trailer and another 2000lbs of toolbox and parts. I am going to upgrade my axles to 2 5000lbs since my frame and deck are heavy duty and I've technically overloaded the axles from time to time.

Re: Might be towing one home!
Oh, and brakes on trailer and vehicle. Test them and know they are good.

Re: Might be towing one home!
Make sure the tires on the Burb and Trailer are aired close to max and go by what the tires say on both, a lot of times the Mfg tag on the Burb will be different than what the tire Mfg says. I loaned a trailer to a guy and he was hauling a 1/2t Chevy W/O an engine with a 1/2t ford and it started swinging on him he put it in a ditch- I think it was due to light tires on the ford and no brake controller to slow him down. If you haven't towed much before take it slow getting up to speed and make sure you have good tongue weight..

Re: Might be towing one home!
Thanks for all of the thoughts guys. Lots of nice safe trailer info here.
I've towed quite a few HEAVY loads with this trailer. The Burb is somewhat new and replaces a former 3/4 ton Burb, (which was a towing MONSTER!) so that will take some getting used to. I do have a good set of brakes, a great brake controller, and ALWAYS air up the trailer tires to MAX inflation when hauling the big stuff. In my towing experience, good towing is about BALANCING the load well. One trick I learned from a friend on ensuring you have enough (but not too much) tongue weight: Start out with the tow rig and trailer on a dead-flat surface. Drop your trailer's tongue jack so it's about 2-3" above the ground. Load up the trailer by having a spotter (or get off and keep checking) and pull forward until the bottom of the tongue jack juuuust kisses the ground, then stop there. For my trailer and truck, this usually gives me plenty of tongue weight but not so much that it's all hanging off the back of the truck driving your hood into the sky. Keep the thoughts coming! |
