I originally bought a cover for my travel trailer in 2015 that came with a 2 year warranty. After 20 months it began falling apart due damage from the sun. I filed a warranty claim that was approved and convinced to "upgraded" to their Tyvek cover for $100 plus $35 shipping. According to their product description, the Tyvek cover had a 3 year warranty. After 2 years the new cover began falling apart just like the first. I called to file a warranty claim and was told there is NO warranty on replacement covers even though the product literature states it has a 3 year warranty. I will never buy their products again . At this time I have over $500 invested.
