11 National RV Dolphin Problems: Common Issues and Solutions

If you own a National RV Dolphin, you may have experienced some problems with your vehicle. The National RV Dolphin is a popular Class A motorhome that is known for its spacious interior and comfortable ride. However, like any other vehicle, it can experience issues that need to be addressed.
An interior roof leak is one of the most common problems reported with National RV Dolphins. This can be caused by improperly sealed seams, missing caulking, or worn rubber seals.
Fortunately, this is usually an easy fix involving resealing the seams and making sure any openings are properly filled with caulking. However, if left unaddressed, a roof leak can lead to more serious issues, such as water damage to the interior of your RV.
Another issue that some National RV Dolphin owners have reported is stability problems. Driving a large vehicle like a Class A motorhome can be challenging, especially in windy conditions or on uneven roads.
