Oh, many of us do not transport our rvs with the fridge turned to gas. There are sites that say it is dangerous to have propane in the pipes that run under the trailer in the case of an accident. They could rupture and cause an explosion. Food should stay fine in the fridge for 5-6 hours if you cool the fridge down for several hours before a trip, only put cold food in it and put some ice packs in if you are resells worried. But many disregard this.
