I took the G3500 to the gravel pit to weigh it, on Monday, when I went to Kevin's shop.

Any guesses what it weighed? (Keep in mind it was only a cab and chassis at the time.)


While I was at Kevin's, I did a lot of measuring.

Here are the two build options:


1. The easiest option is an 8 foot Flatbed with sleeper box.
I can have an 8 foot long flatbed with a 60" to 63" sleeper box the way the truck sits now.

My second option (with this G3500) is more complicated.

2. To have an 8 foot truck bed with a 60" to 63" sleeper box.
I would have to remove the current fuel tank currently located in the back of the frame.
Then remove or shorten the frame in the back by 14 inches.
The above is due to where the wheel wells on the truck bed will line up and how much longer the frame would be past the end of an 8 foot bed.
Then I would have to add 21 to 22 inches in the middle of the frame so it would be long enough for the same 60" to 63" sleeper box as used above, in option #1, and all this before the 2001 to 2019 8 foot long truck bed was installed.
The middle of the frame has to be lengthened due to how much of the truck bed will protrude forward of the rear wheel wells.
Once the middle section of the frame was lengthened I would have to find and install a side mounted fuel tank from a pickup truck.
I would also have deal with everything involved to lengthen the driveshaft(s).
Then install the sleeper box and truck bed.

BTW - I will be weighing the truck again, when I go to pick it up and the flatbed has been made and installed.
And I'll weigh the truck for a third time; "IF" I'm ever able to buy, pickup and install the sleeper box that I want. Grin

Are you sure that this will not put the truck over the GVW rating of the truck's axles? Some of these 1 tons only had 4000# front axles and you are adding a lot of weight.

RJ,

I wish I truly knew. I strongly believe it will be okay and I know what the front and rear axle loads are now, without any of these items on the truck now..
BTW - This truck does not have a factory GM sticker.
It was made into an ambulance / rescue vehicle with a very heavy box, filled with equipment.
It came with a sticker from the body company.

Currently the rear springs are very stiff and fully extended.
They don't show any signs of movement due to the fact that there is no weight on the back.
When the truck goes over bumps the light rear section of the truck bounces all over the place without the spring moving.

Isn't there a website that you can enter the V.I.N. into, and it will tell you EVERY SINGLE SPECIFICATION about said vehicle?
I know that we used one when I worked at the dealership, but that may have been a special access site. I don't remember.
.
As for weight, just tell us and quit the games.

There might be ones for regular vehicles..
Not sure about a site that would work for a cab and chassis, where a body manufacturer finishes the truck and makes it into what the customer wants.

Mel,

I did try a site. I don't trust them. See why...

It says the Gross Combined Wt Rating is (lbs)13,500 for my truck.

But on one line it says it has the 6.5 Turbo diesel.
Then on another line father down it says it has a 350 V8
Then it goes on to say what the front and rear curb weight should be.
FUNNY thing. With nothing on the frame my current numbers, when I weighed it, for the front and the rear curb weight are already higher than what they provided. LOL

Then there is this:
The site says the Wheelbase is (in)177.0
HOWEVER, it is only 159" WB with 101 from center of rear axle to back of cab.

So do I trust the 13,500 Gross Combined Wt Rating? LOL

Then, I would contact the Original Manufacturer(GM), state your V.I.N., and ask them.

Thank you.

I did try that. But I can not recall the results.

I think they told me that because it was a cab and chassis that they cannot get any info. LOL - not sure why - they made and sold it.

Unless the ambulance builder change the suspension like adding an axle the GVW listed should be the same as made. They have to list the GVW since they up fitted the truck but unless they changed something they don't want to take over the liability from GM so they just relist what it was built with.

Well, I've seen different numbers, load ratings, and such listed on different VIN sites.
So I have no clue which one is the correct rating and such.

The last site I used tonight said there are 3 rear leaf springs.
I'm not 100% sure and I will know when I go back to Kevin's shop.
But I thought my G3500 had 4 leaf springs vs 3.

UPDATE on Progress of G3500 project.

Well the truck sat for a week at Kevin's and the only thing done:

1. We went over what I wanted in the way of a flatbed design and we measured to make sure I will be able to pull a gooseneck in the future.
NOTE: How long the frame is and where the end of the flatbed will be; makes it a close call, without having to angle the corners.

2. I went back there, at some point during the week, to see what batteries it had, to order new ones, and to do some electrical diagnostic work.

Kevin assures me that he is going to start on the flatbed this coming week.
I hope so. I need it the following week to get my part.
Electrical stuff is not my strong suit. Grin

This morning my PMD relocation kit arrived.
It will allow me to put the PMD in a place where it will get more air to keep it cool.

I'm still waiting on the following to arrive:

1. Wiring kit for the brake controller for the electric trailer brakes

2. A different gooseneck hitch than the one I first purchased locally.
( The one I first got, in a hurry, from a local trailer place did not have all the pieces with it.
Plus they would not give me any more off the price; so I could get the parts I needed on my own to complete the kit.
I went a head and ordered another one that cost less and came with everything. I'll be returning the first one! Grin )

LOL

I had started typing this some time ago and walked AFK for some time to do other things.

Since then the second gooseneck hitch has arrived. Grin
(It was $20 cheaper, no shipping cost and it came with all the parts, the other place would not take care of the missing parts for me.)

The guessing game:

Any more guesses what the G3500 weighed? (Keep in mind it was only a cab and chassis at the time.)

SO FAR:

1. Craig @ 6,900 lbs
2. Matt @ 6,400 lbs
3. John @ 3,400 lbs


I'll post the answer, for what the truck weighs now, in a week or two, when I pick it up with it's new flatbed and I'll get it weighed again.

I'll then ask for guesses for what the flatbed weights. ggg

And I'll do it one more time "IF and WHEN" I have the sleeper box installed.

I was out at Kevin's this morning to drop of the new Gooseneck hitch.
The diamond plated steel was delivered this morning.

It also looks like the ambulance company, who put the box on the cab and chassis, beef up the suspension on the G3500.

Instead of 3 leaf springs per side. It has 9 leaf springs per side. See for yourself.



Or was it a 5 spring with 4 helpers.
Either way it has more springs than stock.
It also explains why the rear is so stiff and it bounces around so much, with no weight on the back.

This morning Kevin lifted the flatbed frame off the truck, that he is building, so he could finish welding everything.



Then it goes back on the truck and he continues on.

For those curious and interested.

The truck weighed 2,400 kg or 5,291 lbs with nothing on the back.

If all goes well, I'll be weighing it again on Friday with the new flatbed.

YEP! And it has HD springs at least on the back.

Looking at them and what I recall from my days of wrenching on cars; It has 5 leaf springs connected to each other and 4 help springs below for a grand total of 9 leaf springs each side. (see picture in post above)
