In advance of building out an exploring platform for the warmer months, I was starting to piece together a kit for the crossbars. I had a leftover Yakima SkinnyWarrior that I attached alongside a Kuat Trio. Having the space, and wanting to add a semi-permanent tool/accessories box, I started looking into options for something I could add alongside the other two that I could mount directly to the crossbars. I didnt want to have to buy a whole LocknLoad system or similar, having already fit the Kuat and SW so it was a matter of dimension hunting and I landed on the Roam 95L as it looks quite fetching, is quite overly capable in terms of durability, and more importantly, would fit almost perfectly beside the other two items.

In the hunt for mounting options, i wanted to be able to come up through the box with the bolt instead of having to hunt for a nut in the T slot of the cross bar and after some searching here and elsewhere, landed on the 3/8 carriage bolt to run in the crossbar slots. One thing that helped immensely was being able to take the bolts and have my local shop shave down the dome of the bolt, bringing down the height of the dome and allowing for much easier travel in the crossbar. Likewise, it allows me to leave everything intact when attaching and removing the box and being able to slide the box on and off the bars by just loosening the nuts, without having to take it all apart to remove it from the vehicle.

What was tricky was having to measure out the holes I would need to drill in the Roam box. As the crossbars - over the bed of the R1T - are about ~32.5" apart if memory serves, those measurements landed on different places, and heights, of the molded Roam box (seen in below photo), so I needed different lengths of carriage bolts to anchor the box, and allow less protruding up into the interior of the box.

After some trial and error, I landed on the 1" for the front (top of photo, lowest part of the Roam box mold, closest to front of bed) and 1.5" (bottom of photo, taller part of Roam box mold, closest to rear of bed)

You can get an idea of how much the bolts protrude into the box from the above photo. Should leave ample space for some locking washers as well as loosening the bolts to slide the entire box on and off the rails, without taking the hardware out.

And lastly, a photo of all the crossbar accessories and extraneous photos of the bolts used, the last one depicting about how much I shaved off the dome of the bolt to allow easier travel along the crossbar.

I'm sure there could be an easier solution, but the process was fun to figure out and if anyone else is keen on mounting a Roam box for around $20, this was not difficult at all. Sorry for any confusion in my wording, this is my first write-up over here. Hope it helps someone!

Hopefully I'm not buzzkill.

I also have a 95L Roam case and before I ended up with a Xtrusion Overland bed rack, I was looking at doing this same thing, using the Roam Rugged Mounts for the 95L case (https://www.roamadventureco.com/collections/rugged-cases/products/95l-rugged-mounts). Just a tad more than $20 though ? ...

I now just have the case in my bed, locked down with some straps.

This was my inspiration (don't remember the username):

It's a great setup you posted, zero buzzkill!
I was a bit hamstrung as I wanted to use the existing crossbars, not have to buy a base rack or platform, and likewise use the other components I have (SkinnyWarrior, Kuat Trio that were already mounted). The Roam rugged mounts wouldn't attach directly to the crossbars, given the locked distance of the stock bars when mounted so I had to improvise. Hopefully having precise drills and keeping those holes underneath the box will keep any waterproof concerns away (thinking out loud here on an unrelated note)

I'm confused. The picture posted above shows the Roam Rugged Mounts on the OEM crossbars.

You might want to get some silicone on those mounting holes just in case.

Oh wow, youre completely right, my bad. I read that wrong. I was under the impression they were in a fixed position and the distance did not line up with the crossbar width but I guess i'm wrong.

edit: I guess my DIY could still be useful to someone who doesnt want to spend the extra $200 in the end

Not apropos to the recent discussion, but I managed to get my hands on a slate 95L and the lid organizer this week. Using it to store all of my camp kitchen gear and some other bits. The case fits nicely in the R1T bed and will be effectively secure with the RTT mounted on the crossbars.

Haha no prob. I thought I was going crazy. Before I went with a bed rack, I went through this exact thought process and took lots of measurements. I got very close to putting an order in for the mounts. My research led me to finding that green truck with the exact setup I had in mind.

In the end, $20 is a lot less than $200+ and if it works for you then I say mission accomplished!

I have this case and love it too. Use it for various camping and car items. Wish I had somewhere to mount it for camping but the RTT on the back, awning, roadshower and privacy tent on the roof. So for now it lives in the bed up against the wall. I put some straps on it to make it easier to pull out.

the lid organizer is great too, it just fits like crap - I think about half of the holes line up for the bolts.

But thanks for the write up! Will keep this in mind if I find somewhere to mount it.

Yeah it took me a few tries but I finally got most of the bolts installed. There are a few with minor thread damage hanging around here somewhere. ;)

Do you have any sense yet of how big a range hit your setup is causing?
haven’t had it on for any substantial miles yet, but the dimensions, not only for the fit with the other components but also for height tucking well under the roof line were a big part of the decision on the roam box. So I’m hoping that having it close to the rear window and under the roof line should help in some small way

But no I haven’t had the opportunity to test it out yet on a long trip.
