5/4 RPO CUCV or Civi?

[JeffHK5]

Are there any Military specific RPO codes that might help me figure out what my truck is?

Truck is a '88 350/th400/205/60/14ff , 3+3 , has US Government door/glove box placards , with advertised payload of 2,643 lbs.

Original color was red with gold stripes , I'm thinking Forestry Service.

I was thinking that the parts 5/4 I bought years back had a 2,634 payload , where there ever Civi 5/4's?


Where the Air Force and Parks Service 3+3's based around Mil Spec trucks or Civi models?

I haven't ever seen a 5/4 with a gas motor. They all had 6.2's. Now maybe the FS had some gassers. Does it have a Detroit in the rear cause all Gov trucks did.

 

[JeffHK5]

Don't know on the Detroit , haven't pulled the cover.

Has the "g80" diff code which I believe is a Gov-Loc in Civi trucks but I've heard it's also the Detroit locker code in the CUCV.

Is the 2,634 payload a standard capacity in SRW 3+3 K30 trucks?

they consider the "half ton" blazers 3/4 tons and the typical 1 ton srw trucks 5/4 ton. just one of those goofy things the govt did.

 

[JeffHK5]

But would a civi "1 ton" have a pay load marking of 2,643 lbs, I was expecting to see 2,000 ?!?

Is there a pay load in lbs marked on a CUCV 5/4 , you would think 5/4 or 1 1/4 ton would equate to 2,500 lbs..

The crew cabs used in the Air Force had 350 gas engines in them.

The civi "1 tons" and the CUCV "5/4 tons" had the same, or similiar, load capacities. The reason is that "1 ton" has not been an official term used by the manufacturers to describe a truck for a long time, rather it has become a slang term that a lot of the public uses to distinguish between a "1/2", "3/4", or "1" ton pickup. The military simply saw that the truck was rated to carry 5/4 tons and called it that.

A long time ago the heaviest pickups had a 1 ton capacity, but most "1 ton" trucks for quite a while now far exceed a 1 ton payload capacity, even most "3/4 ton" trucks and some "1/2 ton" trucks exceed 1 ton of rated payload capacity. Chevy/GM has offered "3/4 ton" trucks (aka K20, K2500) series trucks for a long time with GVW's of at least 8,600 lbs., so with the base truck weighing 6,000 lbs. that gives it over a "5/4 ton" capacity. A lot of the "1 ton" dually's have had GVW's of 10,000-12,000 lbs. for awhile also.

If your truck is a 3+3 it's not a CUCV. CUCV's where only the regular cab, longbed K30's and the K5 Blazer variants.

However the government bought LOTS of civilian spec trucks from GM over the years. That does not make any of these trucks a CUCV though.
