All services just done. Anyone have issues with New Air Filter needing to be replaced within 3000 miles or less?

Does your have the vacuum gauge that indicates when the filter is spent? What specifies the 3,000 or less change?

Thank You for responding.
Yes the Filter Monitor was showing time to change. Strange thing miles on Rv were less than 3000 since replacement. All travel was highway no dirt roads. Not sure how it can be bad that fast,
Changed Filter and RV runs properly. Before Air Filter change had no power also no codes.
