To locate an RV fender skirt, you will need the manufacturer name of your RV and the dimensions of your original fender skirt.
You will need the following measurements and information:
(A) Top Length - Measured from hole to hole
(B) Wheel Wall - Measured from the lowest point on the outside leg to the highest point in the wheel wall
(C) Overall Height - Measured from the lowest point on the outside leg to the highest point overall
(D) Outside Leg Width - Measured from the side of the fender skirt to the inner side of the leg
(E) Inside Leg Width - Measured at the widest point at the bottom of the inside leg (Not always applicable)
(F) Overall Length - Measured from the longest points of the fender skirts
Axles - single, tandem or triple?
Do the bottom of the legs curve underneath the RV?
