Pintle Hook that Can be Used with Military Trailer M1101/M1102  

I am trying to figure out how to tow a M1101 or M1102 military trailer behind my 2018 F150. I cant figure out the lunette size on the trailer and therefore cant figure out which pintle mount to purchase. The trailer is a government auction so there is no way to access it to measure. This is a common trailer option so I thought Id ask here. I know Ill need an adjustable height mount but the ball size is what Im trying to figure out or if it is better to go with a pintle mount with the hook style closure. Thanks
