I don't mind the strap at all. The Retrax cover has ultimate trouble with binding since your always pulling it open from one side or the other. It doesn't retract on it's own either like the Roll n Lock.
Check this tailgate seal out from Keko. I did a lot of research and decided I liked the complete seal you get with this one due to the brackets they add on either side. Affiliate link on Amazon below.
Yup and that big gap I didn’t like either. I would like to see Realtruck update the bracket design lowering the horizontal flange by 3/16” allowing a better seal to the truck. Everyone that installed it should get new brackets
I also didn’t like the 1/4”ish gap between the rails and bed. This is due to the custom brackets that aren’t the right height. They hold it up off the bed. I think they took a standard product and just whipped up some Ranger brackets. I made a video about it.
GM bought back my lemon Canyon pickup. They paid for genuine GM parts and my Realtruck tonneau and aftermarket rust proofing. You must provide receipts for everything. I believe the Ford tuner should be reimbursed.
