Hope you have good luck with this roll top.Retrax had a special offer of a free Bedmat when I ordered my ProMX. It showed up on my front porch yesterday. Only issue is that it has to be at least 68 degrees before you can install it. While the temperatures in NE Indiana have been all over the map lately hoping for 68 degrees any time soon may be a bit wishful.
I put one on my S10 years ago and the problem I found was pine needles / wet leaves, etc would get into the inside and clog the drain holes about every 2 years I had to take everything apart because so much crap had gotten in there that it would not open or close easy.
Now don't get me wrong. Loved it up until I sold my truck (12 years) to buy the ridgeline, just not sure if I would do one again.
