Roll-N-Lock 447M-XT

I installed the cover and it works as far as the retracting and closing of the cover, I definitely love this more than the roll up cover I had on my last truck. It also clicks and stops in place so you can have it partially open/closed, that's an awesome feature. However there are spots where water enters into truck bed at the corners. Where the drum is, I attached a picture that shows the gap, I think this can be corrected if they cut the weather stripping in correct place instead of overlapping each other. At the rear of the bed there is a gap between the cover and the rails that lets water in. However I have a bed floor mat so most of the water travels down and underneath the mat so it's not a huge big deal but enough for me to not store tools in the truck bed, to keep from rusting. If they made it to where there was like a wedge seal on the rails then I think this cover would be perfect. I attached a picture of it as well, where the gap is. I also think the gap may close up if you mount the rails about 1/8” or 1/4” shorter than what the directions say, I have not tried this yet, I may try it at an 1/8” shorter to allow for expansion/contraction of the materials but still be smooth for opening and closing the cover. Or I may try to find a rubber seal in shape of wedge and see if that works. Whichever I do I will try to post a follow up afterwards. Overall I really do like the cover and would buy it again if these issues were corrected. Lastly, the installation instructions could use some work to make it easier to understand.

This 124M-XT is my second purchase of a Roll-n-Lock retractable cover. My first was a 2017 Chevy Colorado 261M-XT with a much stronger and more reliable retractable mechanism than the current 124M-XT. Are there simple instructions available for me to tighten the spring and improve the retractability.
