What is important is that you realize that this generator "set" as it is referred to, since it is a special unit, includes the trailer. Once separated/ modified, it is never the same. It needs to stay together, but far be it from me to tell you what to do with your unit. It looks to me like it was made for powering light strings in hooches up on firebases and forward operating posts. Small to be air portable, and easy to move with a jeep on the firebase, and diesel so it can handle the constant load for long periods while keeping fuel use down.
I suppose it could be for a field hospital, but I have little knowledge of that.
