Down the road with fridge on propane

[ClassBee]

Whenever we try to run down the road with our fridge on propane, it always blows out once we get up to the speed limit. We have a 2004 Roadtrek, 190 Popular. What can we do to prevent this? We usually just put it on battery, but it's a pain to move it to propane when we stop for a length of time. Thanks.

Leave it on battery when you're driving. Disable your coach batteries before refueling.
The pain from severe burns from a fire are a lot worse.
Seriously.
