I have the TonnoPro tri fold on it's 3rd truck with no issues. Sometimes I wish the front section would fold up behind the rear window for access, most times I'm happy with the way it is. Gray tote and firewood ride under the front section and arrive dry even in hard rain.
Unless you don't have enough bed clearance to begin with the cover will not interfere with anything.
It's been on a 99 Chevy, a second gen Ram, and a third gen ram over a 6 year period. The vinyl has held up very well. I have had to use dots of weather strip adhesive here and there on the seals where they fit against the metal edges of the cover.
I'm very satisfied with the product and would buy another.
