Pintle sizes.....
Just a quick follow up......
The typical Dodge M37 trailer... the M101a lunette is 6 1/4 inch across compared to 5 or 5 3/16 on two different CMP trailers...... the cross section of the ring/lunette is 2 1/16 for the M101a compared to 1 1/14 to 1 3/8 for the CMP trailers......
That implies that the M101a lunette is a very tight fit on a CMP pintle..... almost to the point of eliminating any typical rattling associated with pintle towing.
I have attached a hand drawn sketch of the cross section, viewed from above, of both pintles which have noticeable differences......
The CMP design is such that the lunette curve of the ring fits much tighter than the reverse open M37 style..... and they call it progress. In the CMP model any braking or decellaration would be better captured by the curved feature of the pintle....
