You asked which I preferred, the original (sunbrella fabric?) or the vinyl looking material from Tough Top. Well, our last two coaches had the original material and the stitching in all of them failed along with developing small holes that would need stitching. Looking not to repeat those issues, I went with the material from Tough Top. Give me about 10 years, then I can make a better comparison.
As far as appearance, the slide out covers are not exposed much, not like your patio awning. So if they look cheap, you can't really see much of them . Cleaning the Tough Top is easier, I never could get the dirt and grit out of the original material.
