I installed my Pro X15 last week and really like it. I’ve used roll up soft covers for years and they fit my needs perfectly. I average about 10 to 15 trips a year getting mulches for my landscaping. Rolling it out if the way is ideal. Security isn’t an issue for me, I’ll put items like that in the cab. This summer I’ll be loading bikes in the bed while pulling my trailer and this it’s just an easy solution.
I picked the X15 for the fabric, low profile, allows access to the stake pockets, and hopefully solid quality from a name brand.
