ok, the hem museum sent me some pics. but there kinda huge.
dont know if I can get it loaded or not.
but the what thay did was, build a steel box on the trailer a little higher than the sides. and mounted the pedistal antina in the middle,
then put on jacks and outrigers.
so its not a roll off like the other one.
its integral to the trailer.
this is the last K-number I'v been able to find.
evedently thay went to a V-number for AN- stuff.
and thay still use the V-number today.

Sumpin looks wrong here:

I could not find that pix in the TM9-2800 from 1943

Four (4) 7.50x20 tires I do not believe will carry 7 tons (14,000 lbs)

The other trailers like that are rated under 10,000 lbs GVW.

The next trailer with 7.50x20 tires that I found with a 14k GVW had 8 tires on it.

Hmmm

the pic is from the 1947 9-2800,
if you dont have it I highly recomend it.
I think its more better than the 43 couse it has more late stuff in it.
the radar guy says thay only built 80 of these.

I have that one too along with the 1953. I just have to find it...

Does it say 7.50 x20 tires?

I will have to read the specs on the sidewalls of the tires on my CCKW.

it say 10 ply 9x20
it also say tow truck is a 4 ton 6x6 or greater
TM-9-873 snl G-714

this one is 48 1/4" between the axils, looks like the standard one is 40"
between the axils

Must be some different than the M7 series.

My SL trailer had 8.25 or 8x20 tires on it and they had to put washers behind the wheels to prevent the tires from hitting the suspension.

Brian,

Great pictures...Thanks for taking the time to post them.

I note that the wheels are the same as used on the larger capacity vehicles. They have the 10 lugs instead of 6. That would tell me a much higher GVW.

They are obviously a copy of the WWII version of the G-221 but have been modified.

David Doyle's book about High Speed tractors has a picture in it of an M-4 HST pulling these in Korea.

Great info!

Bill
