Interesting some of the GL trailers coming up for auction have some pictures of the M101 in the tilt position. They are starting to market them as tilt trailers. A number of trailers up for auction have a set of pictures of the same trailer in the tilt position, and they say this is not the actual trailer being sold, but is a representive sample of the M101 trailer in the "tilt position" for reference.
They probably should not be doing that as people will get the wrong idea, not understand the hazards of the damage they can do, and if it is not intended to be a dump, it just doesn't make sense to advertise it that way. None the less, I would not hesitate to use mine as a dump, as, for what they cost, I would just replace it or the parts if it went caput.
This is not a recommendation...
Doghead and the others are on the mark more so than I.
