Being able to predict the weather while traveling in an RV is, in my opinion, quite valuable. It's helpful to know whether you should pack your belongings because major pressure changes indicate that a storm is on its way or whether the wind has shifted and a storm is approaching. It's not only for pleasure—it's for your own safety and the protection of others around you. It's always a good idea to be prepared. A weather station will provide you with interior temperature and humidity levels, which will assist you in regulating and preventing mold and bacteria growth.
