Info on the tank off a M149

[juanprado]

I was wandering if anyone has had experience with the the 400 gallon steel round tank off a m149 on mounting it on a m105 trailer chassis?

Is the m105 trailer chassis without a bed the same as the chassis of a M149? or

Does the tank mount flush on a trailer bed with the four feet that mount it or does it have to bowed?

Thanks for your advice!
