They have a top mount for the Maxtrax. RRAC104Installing a full length roof rack was one of the first mods to my 2016 TEP. I selected a Front Runner because I liked the idea of bolting down the front feet. I wanted to make sure my rack didn't vibrate at speed.
After a successful installation, here's what's great about FR:
1. The thing is surprisingly solid. It's really impressive. I grab ahold of the rack and shake the whole vehicle with no discernible flex in the rack. It is very rigid.
2. It supports plenty of weight. We occasionally climb up on the roof rack to secure items in place.
3. FR makes tons of accessories and attachment devices.
4. It's really pretty quiet. I briefly installed the expedition rails, but hated the wind noise. And I couldn't keep the bars from rattling. I took those off, and everything was perfect. No major wind noise.
Here's what I didn't like:
1. I didn't mind drilling the holes in the roof for the front feet, but the rivnuts we're awful. I spent a lot of time measuring sheet metal depth, and looking up rivnut specs. The sheet metal at that place in the roof was double thickness. The rivnuts did not have the grip range to be set there. I emailed FR, and they said they would send me bigger rivnuts. I got four more rivnuts a few days later that were identical in size. I ended up dropping the headliner and using a large fender washer, a regular washer, a lock washer, and a nyloc nut from below to secure the bolts through the front feet.
2. Although FR has plenty of accessories, I just haven't been happy with the various options for attaching the awning or the Maxtrax. The Maxtrax solution puts them off the side of the vehicle, rather than on top. I ended up modifying a side mount to work with the Eezi Awn awning so that it could be mounted right along side the rack, rather than up above it with the FR-recommended bracket. In brief, I often look at K9 solutions and wish I had gone with a K9 rack.
Overall, the FR Slimline II full length rack is a solid option and I'm content with it. If I were starting over, I would choose another rack, however.

I've had issues with the supports corroding. They were more than willing to ship me new supports.
