I have friends who converted a school bus. They put in their 30" lp gas range and run the 110vAC stuff (ignitor and electronics) off the inverter so they can still bake if the power goes off. Their thoughts were the largest rv range required a 24" cabinet space to install. The residential slide in range required 30". Only 6" more. Since they are fulltimers and like to cook/freeze meals, they opted to keep the residential range. They say the residential range cooks far better and uses 1/4 of the lp that their rv range did plus they cook far more now and still only go thru a 20 lb tank in 3 or 4 months. Pretty good considering how heavily they use the range. It's enough to convince me to convert a school bus and build it like they did, using mostly residential appliances, etc. They put the burner grates, spreaders and caps in the bottom drawer (modified to lock) while traveling.
