Has anyone done any Mods to the rear sliding cargo area for T4R with sliding deck. I'd like to put a cooler or storage under this tray that slides out.

Dude you have like 3/4 of an inch between the sliding tray and the floor. I guess you could build a cooler to store bacon or Slim Jims or something but that's about it.

There's a little room underneath for some gear.

Initially I thought the built in tray was a good idea.

But as is it doesn't cut it. Gear slides all around and falls off as you pull it put.

To remedy this I installed some Macs Custom tie downs to secure my ARB fridge, some Wolf packs/Bundu boxes (& on other side my Viaair/recovery bags/etc).

I have different boxes I swap in for fishing/camping/etc.

I didn't want to do a drawer system at this point (weight/cost/flexibility) so this has worked so far on some long distance camping trips, offroad & day to day. Im satisfied with the flexibility.

Sorry this is the only pic I have handy. (Boxes not strapped down in this pic)

Screw the cooler then! You need to flush-mount a George Foreman Grill in there and get that bacon cookin'!!

I pulled the back lip off mine and I store some gear under it.....is that a mod??

That's a bigger mod than some of the guys who start "build" threads ever accomplish...

you have a little over 1.5" of clearance I use mine to store tools I also ordered a piece of polyethylene foam to keep everything in place like a gun case

Oh, that is a great idea. Maybe that is why I asked for your Mods to see what you have done. I am thinking of taking the rails off and build a box to mount the rails on with storage underneath.

I'm glad you elaborated on your thought. I was kinda wondering what you were trying to say and how your were going to fit anything under the sliding deck, short of cutting the floor and moving the spare.

Im thinking about taking mine out and going from there.

Dude, I know this is an old post, but that's exactly the kind of thing I was looking for. I don't want fixed drawers, as I need a more modular system. I use a 70 qt Coleman Cooler and 15 gallon Sterilite Industrial Totes for a modular system to hold gear, food, etc, keeping part of the gear in 2 totes on the sliding deck along with the cooler and the rest separated onto the folded down back seats, where I can stack up to 6 of the totes. A lot of times I leave half the sliding deck open for the dog. I need an anchor system that stays with the deck as it slides. Not sure why Toyota put all the anchors on the floor where they won't slide with deck.

Anyway, did you just drill and bolt directly into the sliding deck? Anything special?

Finally made the mod to my rear sliding cargo deck to allow easy tie down of bins and cooler. The system is modular, unlike a drawer system, and very lightweight, inexpensive, and functional.

I drilled and bolted cargo track into the rear deck, which allows securing of a 70 qt cooler, 2 - 15 gallon sterilite bins, and some extra free space all on the sliding deck, which can then be pulled out, like a drawer, without anything falling in the opening behind the deck.

I bought Airline track from uscargocontrol.com
3 - 24" pieces in black AT24BL
1 - 48" piece in black AT48BL
3 - ATFASTPACK Stud Fitting Track Fastener 10 pack for securing the track to the deck
8 - 1529-DS Double Stud Fitting 5k B.S. - These fit in the track and allow tie down with straps or hooks

I had to cut one of the long pieces with the dremel (fairly easy) to fit across the back of the deck.
I laid down the long piece across the width of the back of the deck, and the 3 short pieces oriented length wise. 2 of the short ones are spaced just enough to fit the width of my cooler (or most coolers that size). This allows bins or other wider items to fit on the other side.

I kind of wish I had put the narrow side on the other side of the deck now, to allow the cooler drain spout to face the outside and allow the cooler lid to open laterally. Just something to consider.

Lay the track and mark the drill holes. Feel the underside of the deck to make sure you don't drill through something important. I drilled right through the Canvasback cover, carpet and deck easily. It is a kind of foam core, so little white bits end up everywhere. I just used washers and bolts on the underside to hold it in. I think there are enough bolts that it feels pretty sturdy, despite not super strong material in the deck. I lined the track up fairly close to the edge of the deck, but not too close to hopefully give more strength.

I use these Sterilite Bins:

Only $10/ea. Decently sturdy. Can stack 2 high in back of runner. Can fit up to 10 bins in back of 4Runner if back seats are folded down. I generally set up with 6 bins, a 70 qt cooler, and a dog. These are also just low-profile enough to strap down on the gobi roof rack as well if you need more space inside, and will be fairly weatherproof up top.

I use the Coleman Xtreme Marine 70 qt. Holds ice almost as good as a Yeti for about 1/7th of the price. Obviously, it won't outlast a Yeti, but I bet 5 of them will:

I use NRS Straps for tie downs.
2 - 4" Red straps tied to cooler handles to allow opening the lid without strap removal.
1 - 7-8 ft strap around the body of the cooler to prevent accidental opening when on the move.
3 - 6' loop straps for tie downs
2 - 9' loop straps for tie downs.

The problem I haven't figured out is: How to tie down items over the rear seats when they're folded down. There are two stock tie downs there, but they are in an awkward location to be functional. I'm thinking a cargo net is needed. Any ideas? The goal is to not have items overlap the gap when the crago tray is pulled out.

I little off topic but distantly related -- anyone ever seen any custom gun enclosures made for the rear of the 5th gens ? Need to be able to securely store some firearms and havent seen anything good yet.

Are you thinking of something where you pull the slide out and that exposes a lockable hatch / compartment?

Nice cheap setup, cooler on one side can be tied down at the handles and still opened on the sliding tray. Fit 2 bins next door plus some space for a duffel, etc. Highly modular.

There's something to be said for keeping it modular.. looks good.
