It’s one of the easiest things to overlook regarding RV safety. RVs can be substantially overloaded but not outwardly show it like a car or truck when it is obvious the back end is riding low. So unless you weigh your RV, you may never know it may be dangerously overloaded and a safety concern.
RVs leave the factory at a safe weight, and most give plenty of extra weight capacity for us to load them up with our stuff. But sometimes, over a period of time, we add things and invent extra storage areas until almost imperceptibly we have bypassed the safe weight.
