Lets look at this big, ole truck.
This guy travels cross country, so this is part truck and part condo. Have a look...
But what about the appliances(your first thought)...Yachts, Trucks and RVs are interesting because they typically maximize space efficiently
Integrated refrigator. Intelligent choice a regular refrigerator would protrude another 12-14inches into the truck/condo.
Convection/microwave combination..Sharp is a decent choice. This trucker can cook, microwave or do both in combination.
Induction cooktop. Fast, less heat in the condo and induction will shut off without a pan (yes, this is a bad pic)
Have a galley kitchen or tight space and need ideas, look at a truck
