I just finished unloading one of those from my truck 15 min. ago. Mine came from a SOB camper my brother sold years ago as junk and pulled out the ONAN it has 41 hrs on it and it is heavy. I am generator rich right now as I live in New Orleans and everyone in the family are installing 16 and 20 KW whole house units and I am being given the old units.
My plans are to put it in a case on large wheels, I will use a boat tank (Quick Connects)to feed it fuel or may convert to propane as I have not read the entire specs yet so not sure on how I want to power it. I will install a 12 volt
winch in the bed of my truck to pull it up a ramp for loading and unloading.
I has to have a case as the airflow has to be directed over the engine to cool. 4kw, 2 cyl and heavy.
