Sun exposure and age can lead to cracked plumbing vent covers on the roof of an RV. Installing a new vent is a quick easy job, completed with just a few simple tools.
Older style roof vents may not match replacement vents, which makes it impossible to simply snap a new cap onto an older vent base. This means having to replace the base, even if it's in good condition.
This is a quick, easy repair, completed without special skills in under half an hour.
We don't pretend to be experts on any particular RV topic, and mostly know about maintaining our own rig. But many systems are the same on different RVs. The advice we give works well for us, but be sure to consult a professional technician if you're unsure about working on your own RV.
