I first tried a cover for a 22' motor home. Was too big, but I gathered up the excess with bungees and it lasted less then a year before a big wind riped it to shreds. Next, a cover for a 20' motor home, better fit, but wind destroyed it too. Then I called King, they sent me a fitted cover for $900 (1998 price). It's still on the boat today, and holding up well. I am sorry I wasted my time and $ fooling around with cheap motor home covers. The King is what I should have done in the first place.....Buck.
