Mr. Lang.

Here's the specs from the 1946 booklet for a 2 ton.

From the ground to the top of the cab is 91 inches. From the frame to the top of the cab is 62&15/16 inches. From the ground to the top of the frame it shows 28 & 1/8 inches. ( I guess that wouldn't be the height of the bed which would be above the frame!)

Should be a lot of fun if you get one of these. You're right! 45 mph is 'race track' speed.
Cheers, Geo.
