I want to add a rooftop cargo box to my 4R but it seems there are not many waterproof roof top specific boxes. Seems many use gun cases but i am not a fan nor am i confident in there waterproofing.

Basically i am looking for exactly this:




Problem is these dumb dumbs provide no way of mounting the waterproof case without making it not waterproof by having to drill holes to mount it. So i would have to do some serious fabrication.

I currently have the stock roof rack and a set of Victory roof rails with my Maxtrax mounted to them so the rails are spaced ~38" apart (box will need to mount in some way at that 38~ space).

I'm down to getting this ROAM box and doing some serious fabrication with some kind of bracket. But i figured i would check in with you guys if you had any better ideas?

I also like the piston the ROAM box uses as well as its low profile. All ill be putting in it is my recovery/emergency gear. Thoughts?

I have the roam boxes as well, they are great. I'm also not a fan of drilling holes in the bottom to mount them down.

I use ratchet straps. On each side of the lip on my roam boxes is a slot to run the strap through. It takes some maneuvering to get it just right to strap it down so you can still open the lid without unstrapping it, but it can be done.

would you consider a rooftop cargo box like Yakima or Thule? those are waterproof

I would, but it would have to be super low profile (~8" H) and be able to fit beside my Maxtrax on the roof.

Good to hear.

I may have to try the straps, the slots may not line up to my rails that are 36/38" apart. I think the slots on the long side start at about 6".

I also spoke to ROAM and the guy said they will be coming out with a mounting system soon.

Also heard that drilling holes voids their warranty. I do not have Roam specifically, one of the Plano gun cases, but I just put silicon around the bolts and threw some desiccant inside once installed. I personally havent had any issues or leaks.

Pelican Cargo Case

Not 100% sure on waterproof. Only seen one in the wild and the dude wasn’t able to tell me too much about it.

Nice cases and similar in price. But all of them start at about 11" high and not quite long enough.

Sherpa makes brackets for those cases without drilling:

Thats how I mounted mine:

Nice find!

Glad someone makes mounting brackets. But i would then need to buy a Sherpa rack for like 1k. lol Maybe i can modify them?

Truck looks sweet. Your ROAM case has been good?

They mount to any extruded cross bar but I'm sure you can modify them to fit different racks. I have it mounted to my Prinsu rack. I actually had to cut off 4mm from the top of the bracket because they sit to high and prevent the case top from sealing correctly. After doing that its been solid. I'll run it through the car wash for watertight integrity and report back haha!

Good to know, i don't have an extruded cross bar. So i will definitely fabricate one myself for an exact fit. Looks like you got the 83L, is it deep enough for most things?

Its got decent real-estate, good for recovery and camping gear. I just mounted it so i haven't placed anything up there yet but I noticed the locking eyelets are tiny. Can't fit a normal size lock so I'll have to use something smaller. Something to think about when determining what to put up there especially for long periods of time

Thanks!

On my Maxtrax i used my cable gun locks since they are small. Seems to work and also implies the gun that used to use the gun lock is ready to be used if necessary. lol
