i have several ex-government generators that I really should sell. There are 3 7.5 KW gas units mounted on trailers. These are real 7.5 100% duty cycle machines built on nice large tire trailers. I bought them all at the same time from the State of Oregon when they went to diesels. They are operational (or were) designed to run unattended for long periods of time. Single and 3 phase all voltage output with great weather proof insturment and gauge panals. I also have a nearly new military Yanmar Diesel portable unit. It has fewer than 30 hrs on it from new. The Military rating is 3KW but the power curve in the manual shows it at 7KW. We are operating several of these and they are a real gem, you can either hand or use the electric starter. Totally weatherproof. It takes 2 guys to handle it. I will sell the gas ones for 500.00 and the diesel for 1000.00
