A broken-down RV can be a scary prospect, but even if you get a tuneup and make sure everything's running well before RV travel, there's always a risk of something going wrong on the road. If you find yourself stuck on the side of the road, the most important rule to remember is, "Don't panic."
These days, you've probably got at least one cellphone on board, and a generator that can be used to charge the device even if the battery's dead. Not only does this give you the ability to call for help, you might also be able to search the internet for the best local towing company or repair shop. If you are a member of the Good Sam Club or any other automotive travel organization, you may be able to contact them directly for help.
It can be a good idea to bring along road flares or other cautionary devices to display on the road near your RV. This is especially useful if you happen to break down on a narrow roadway or a highway with a small shoulder area. Letting other vehicles know to expect your RV gives them the chance to slow down and offer you a wide berth so you can safely inspect your vehicle and wait for help to arrive.
