We are ready to buy a 2008 Icon M-24D Dodge Diesel. It has 113,000 miles. My concern is the generator hours. It has a little over 400 hrs. Is that good or bad?
Generator SHOULD be exercised 2 hours every month. That means an 8 year old generator should have at least 8 * 12 * 2 = 192 hours on it. That is if it is never run except for exercising.
At 400 hours, it has been gently used. No worry there. I would be more worried about a generator with hours too low than one with hours too high. The more they run, the better.
