I did a lot of research and decided on a Front Runner rack for my D1. Because the side rails of the rack are two pieces (which I wasn't aware of when I bought the rack) and the gutter on the D1 isn't completely flat, I had to add shims to get it to sit straight. Then the wide slats caused major vibrations in my sunroof and then the whole truck. Is soon as you got over 30 kpm the whole truck started shaking. Got that resolved and then went to install the Maggiolina Extreme and it wouldn't fit unless I made cutouts at both ends of the rack. I decided to stop at that point and went back to my Thule racks for the RTT for this summer. That said, the folks at Front Runner were great and their service is excellent. If I do go back and add a rack in the future, I think it will be a Baja Rack. This was my second choice and in hindsight, it might have been the better choice. I'm sure they could fabricate a rack for your needs. Right now, we are rethinking our camping setup and looking at selling the RTT and going to a Kodiak Canvas ground tent with a Thule Rocket Box up top for extra gear and the canoe.
