Did a lot of research and decided on the BillieBars.

I wanted something low profile for my rooftop tent, without it sticking too hight above the cab. Ordered the 3.5 inch risers to hopefully gain a few inches to make the side window awning useable, but they are temporarily out of stock. Bars were pretty easy to install, but were a pretty tight squeeze. Might be a coincidence but the bed panels have ever so slight ripples near the top, just under the bed rail cap. I don't remember if they were there before the install. Not a big deal, just an observation. I know they make cars/trucks with paper thin sheet metal these days. One bar was also a little dinged up. Not worried, cause they'll get used and dinged up some more. Bill and Nate were very nice and quickly answered all my questions via email. Planning to add the molle panels soon.

 

Following. Might go with these with my Diamondback cover. Keep us posted OP!
