M1031 Weight

[Matt S]

I've looked around on the site for this but came up empty using the search button.

I took my M1031 to a scale today and it weighted in at 6600 lbs with a full fuel tank.

The generator was between 280 - 300 lbs.

Sounds about right. Mine is 8400 pounds but I have tools in every bin. Plus oxy acetylene, argon and the GTAW/SMAW welder. PTO generator with Champion air compressor stock.

The cab and chassis weight is 5200 pounds.

It looks like the data tag shows #7300 for shipping weight.

That is for the M-880 which was the Dodge with Dana 44 front axle, Wisconsin engine powered Hobart 200 amp welder-generator, single phase compressor and 318 gas V8.

The M1031 SECM body was made by Able Body Company with a 9000 pound GVW. Shipping weight? 22 metric tons. Why? Because that is the displacement in cubic feet (87 based on water weight at 64 pounds per cubic foot.

The contract for the ABC SECM weight was based on the M1008, when the 1031 was finalized, it was given the HD load at 9200 pounds, hence the variation between the body and the chassis. The 1031 contract was expanded as the minus bed was a discount from GM so more chassis were bought than needed. Excess were converted to 1028s

Some early 1031 SECMs were made with salvaged M880 bodies with a small fuel tank added for the Wisconsin engine.

Hope this clears up the confusion.
