Overhead Towers w/ Tonneau Covers

[GhostZR2]

Good morning! I did some digging around and have not come up with many solutions other than the Yakima HD Towers that are compatible with the roll n lock tonneau cover w/rail system. I am looking to find something that is bit more reasonable price wise as $900-$1,200 for towers only seems a little high. Looking to get the towers to transport my SUP to the lake and beach here in NC. Does anyone have any recommendations or insights on what I could look into without having to go with the Yakima as I know they are the best option.?
