Trailer demensions

Ok I wanna get some deminsions of a m101 and m105 trailer

I need a bed on my cab and chassis and I think this would look cool.

Axle width outside tire to tire is 82"

Outside measurements of bed need to be front of bed to axle centerline 56" and centerline to rear of bed 50". Give or take a few inches as I can always move it around.

Thanks for the help. These trailers cost the same as having a headache rack and rear tailgate build for my current flatbed.

Dimensions are listed in the Technical Manuals.

But not front to "axle center line" and "axle centerline" to rear

Width is perfect for my truck 83".

TM 43-001-31 indicates that on the 101 its 58.25" from the front to axle center line and 42 from center line to aft.
M105 is 57 from front of bed to axle center and 53 center to back.

Ok well the tm I found in google only listed full lengths. Is the width outside to outside edge 83" like I found on the 101 because if it is then a 101 bed will fid my dually perfectly and I can just trim a little off the rear frame rails.

83" width on the M105 and 74" on the M101. TM 43-0001-31 is the Tacom Data Sheets. Has lots of dimensions on lots of wheeled equipment.
