Where the real cost usually comes in is the options that are available - most of which are part of the Automatic Transfer Switch (ATS) . Automatic excercising, battery charging, block heaters, low oil alarms, fire alarms connected to your alarm system, etc. are all good options to have but can get expensive..

Cummins makes whole house units.

You're right Steve. I haven't been around the generator installs since I closed shop in 2010 so I just peripherally kept up with the market. If I was in the market the Cummins would be what I would be looking into. At the time I was doing them Onan was only offering the RV units but the whole house units were just being developed. Looks like they are finally getting competitive with their pricing also. They used to be way more expensive than almost everything else on the market...

Never underestimate your ability to overestimate your ability.
