Field office, I build new homes and often I have to drive back to the office to scan or print items during the course of the day, appliance cut sheets, revisions architects send me, etc. It will be so nice to have an on site office with heat especially at the preliminary stages of construction when your constantly in the weather. The house plans are often to big to roll out in my truck, just to be able to do that out of the wind and rain will be great. That's actually the reason I ordered my FWC with flush appliances. HP makes a portable 12 volt printer scanner (I'm picking up soon), my lap top and I'm setting up the truck with wifi. .I think its going to work out great, I'm even discussing possible tax deductions with my accountant. The truth is I work a lot more then I play, my other use for my FWC may just be camping.
