Nice write up! Do you have the dimensions of the platform? The dimensions listed on AAL's website do not look correct.
The base platform (not the shelf) is 38 3/8" wide (approximately 1/2" space on each side) and 33 3/8" deep (interior edge is barely touching the rear side of the back seat).Nice write up! Do you have the dimensions of the platform? The dimensions listed on AAL's website do not look correct.

I have the IronMan4x4 900mm twin drawers installed, they extend 1-2" past the edge of the AAL platform (which has a 1" upward lip). I'm able to extend the driver/passenger seats all the way back and recline.Do you have a picture showing the platform clearance near the rear cupholders and back of the seats? I am looking to see if there will be enough room to have an underseat bag with the platform installed.
Sorry for the confusion. It is only in the cargo area behind the rear seat. With the back of the rear seat in the upright position, it barely touches. You can see how far it extends in the picture with the rear seat folded down.Do you have a picture showing the platform clearance near the rear cupholders and back of the seats?

Thanks for the detailed description!After a few camping trips, I knew I needed a drawer, shelf, and refer slide system. I wanted something rugged, stoutly-built out of metal, a simple bolt-on system, an adjustable-height shelf, and something that I could take out in an hour or two if needed. I zeroed in on American Adventure Lab’s Modular Adaptable Storage System (MASS) with an adjustable-height shelf, fridge slide, and drawers. Not wanting buyer’s remorse, I made an appointment and drove six hours to their location to see their system. When I got home, I ordered one. It is a fantastic system— stoutly-built; precisely engineered; fits like a glove; the slide mechanism is smooth; and the quality of the build, fit, and finish is top-notch.
I have a 37-quart ARB refrigerator with the insulating transit bag cover. When pulling out the slide, the top of the transit bag just barely misses the bottom of the shelf for the first five inches (the latch area) then it clears the bottom of the shelf by about 1/4" the rest of the way out. The bottom of the refer slide is at the same level as the bottom of the drawers. I got two six-inch drawers because the three-inch drawers just looked too small to hold much. The drawers have three removable metal dividers that are cleverly engineered to come out easily, remain rigidly in place, and can be secured with a zip tie at the base to eliminate rattling.
The gap between the top of the base plate and the bottom of the refer slide and drawers is 1/8" (the thickness of the angle iron in the slider/drawer frame supporting the slide/drawers).
The distance between the plastic at the rear tailgate opening and the bottom of the base plate is 5/8" at the edges and 1.25" at the center (the plastic is higher at the sides).
I’m no mechanic and never worked on a vehicle before getting a Jeep. I can do bolt-on accessories (LOD front and rear bumpers, Warn winch, Genesis dual battery system, trail lights, CB radio, Outback tailgate table, SPod, and ARB dual compressor)—especially if there are good, detailed YouTube videos. There is a two-part video in great detail of someone in Singapore (Jeep JL Wrangler Cargo Shelf - American Adventure Lab M.A.S.S. Cargo Shelf Installation - Part 1 and -Part 2) installing the shelf in this system that mounts to the roll bar.
The instructions are good. The guys at AAL are super helpful and will answer any installation questions you have. The fitting that connects the components together was a little tricky to figure out but once you figure it out, everything should fit together smoothly. The bolts securing the rubber feet of refrigerator are re-installed through the slide so the refrigerator is bolted to the slide.
I plugged the refrigerator into the 12-volt outlet at the rear of the Jeep. The plug makes light contact with the insulating transit bag cover (not enough to damage the plug when sliding the refrigerator in and out). I’m going to install an ARB Fridge Wiring Kit with Threaded Socket (Part Number 10900027) at a convenient location near the rear of the refrigerator to eliminate this issue plus the refrigerator really needs an appropriately-sized wire.
I hope this helps. Post or direct mail me with any questions.
Let me know if you need anything else.Thanks for the detailed description!
I am looking at the MASS shelf myself, and I am wondering whether it will work with the soft top. On their homepage, AAL mention that a slight modification to the bracket attached to the roll-bar (an additional hole) was required to install the soft-top. From your picture it appears that this hole is now standard?
Would you mind sending me a close up pic of the bracket attached to the roll-bar, looking from the cargo area towards the side window?
I've taken it rock crawling and down BLM dirt roads--no shakes, rattles, or squeaks. The drawers have three removable metal dividers that come out easily, remain rigidly in place, and can be secured with a zip tie at the base to eliminate rattling.Any shakes, rattles, or squeaks empty and loaded? Looks like nice stuff.
It would be cool if AAL could make a 60% and 40% rear seat delete MASS system.
