And what else could break on this trip...

My wife and I have been on hundreds of trips in various RVs we've owned. Most of the time, we had no problems and all went smoothly. Other times have been the exact opposite (blown tires, getting stuck up to the axles in mud, getting caught in a snowstorm with no snow chains, etc.). Guess which ones we remember and laugh about the most, years later?

Remember, you're driving a house down the road, putting it through what is essentially a continuous earthquake. Things are going to break. As long as nobody gets hurt, any problem can be solved. It's all part of the adventure.
