Welcome to the Irv2 Forums! Here you will learn lots of things about RVs and Motorhomes.
However, to really answer your concern, we need more information. What make, model and year is your camper? Does it happen on both shore power and when operating on batteries? Does it matter if the canopy is opened or closed?
Give us a bit more information on what is happening and someone here will give you guidance.
