Waited to see what GNR is, also.
However, last week we replaced our slide out toppers and one shade awning. Intend to do the rest of the awnings in the fall. Got our replacements mailed to us, post paid in about a week from ToughTops.com. Very pleased with the quality and price. My son and I (44 & 72) installed them in about 30 minutes per awning. (First took longer -- learning curve.) One person pulls product into the slots, the other person simply holds up the excess material. In retrospect, could easily have been done with my wife.
Shopped around here in AZ, best was product plus 2 men x 2 hrs. ToughTop product cost came in at about 80%. And we saved four hours labor.
No commission here, just a tightwad happy cheap didn't turn out expensive!
