In searching for a M416 trailer to use as a camping platform, the only find, at a reasonable price, are beat up M416 trailers. If you find a M416 that has a beat up, rusted out tub, there is an easy fix.
We designed our M-Series Dinoot tubs with the same 40.5″x72″ base footprint as a M416 trailer. This means you can roll the old beat up tub off and drop a new lighter weight Dinoot M-Series tub right on it. The Dinoot replacement tubs are available with and without a tailgate. Once you have your trailer rolling again, cut up your old M416 trailer tub, load it up and haul it down to the scrap yard for recycling.
