28″ Boomerang BladePremium Wiper Blades designed for the RV market by the “RV Wiper Blade Experts”, Tru Vision. They offer the most complete line of RV Wipers available. For your safety, wiper blades should be replaced two to three times per year. The wipers on your RV are particularly vulnerable due to the fact that the RV sits in storage, exposed to the elements, without the wiper blades moving for long periods of time. Now is the time to replace those wipers with the Premium Wipers offered by TruVision. Check online for fit application charts to find the correct wipers for your coach, or contact your RV dealer.
