SeattleMike's cargo project

Mike, looking really nice. With the storage you are adding giving up the stash box is not going to be a big loss. Are you going to fab the storage compartments out of wood? What do you expect the final weight to be? Also, since you mentioned a rooftop tent, what type are you thinking of?
I think TitanPat57 had something other than wood in mind, but I'm not positive on what exactly. There are so many composite materials available today that are lighter and stronger than wood. However they are also more expensive.

The prototype frame weigh 30 pounds as it is. 300-400 pounds is probably at the top end when loaded.

Right now I plan on getting my tent and awnings from GordiGear. Their RTT sits low enough that I can still drive into my garage.

Does anyone know where you can get ratcheting hand cranks?
 
I'm having a hard time envisioning what it is you're doing with the rack based on the computer drawing? Are you doing multiple drawers? Excited to see what it turns into, nice work so far.

The rack just serves to support and secure the drawers, which will sit on top of it. This will allow the tray to slide out and be used as a table or seat. So just imagine the drawing sitting on the rack. It's rough, I know.

Ok makes sense now, + this will enable you to use the cargo rack still as well, right?

How tall are you going with the drawers, how many levels of drawers and what diameters?

The plan is to make it modular. Below is a pic with the sections labeled:
seattlemike-albums-seattlemike%27s+trail+edition-picture1832-cargotwo.jpg


The top of section 1 will be the puppy platform, with the Solvit pet ramp in a slot below. Which of the 4 slots is still up in the air but the ramp is 20" wide, so that should provide some scale for section 1. Section two will be a pantry-style drawer, with some 6.2" wide Oxo containers and and maybe a rack of magnetic spice cans. Section 3's slots/drawers will hold a folding camp kitchen, a stove, pans, utensils, etc. The top of section 3 will also provide another area for storage of recovery gear, clothing, boots, etc.

The steel frame just provides the base. Ideally, we can use the prototype to create a template and get a production version made. Then they can be reproduced, for other people with sliding trays, who can just bolt one in and configure their own drawers to meet their needs.
 
So... the first frame proved unusable. Upon removing it, there were obvious issues with the leg placement and other quality issues that forced me to go to another fabricator. Rather than go back to the first guy, I chose to start from scratch and a slight redesign. Unfortunately, the day I brought the new frame home I came down sick, followed by my wife coming down sick, and things went downhill from there.

So... here is the cargo frame, version 2.
As you can see from this pic, I've removed both the "hidden box" and the risers Toyota used to mount it.

This frame is infinitely stronger than the original attempt and it should provide a good base for the plywood floor that will be going in next.

I should have some more pics in the next few days, weather depending.

The company that fabricated and powder coated this frame was Hell Yeah Custom Coating. They were incredibly patient in working out the design with me, as I kept making changes until it was "right". I cautioned them to keep the measurements (or make a template) so they could replicate it as needed, and while they are not a "production" shop, they got the job done. I also need to stress this is a prototype and may need further refinement before it's all said and done.

Sorry for the delay here, the last few weeks have been a trainload of time consuming illnesses, friends in need, and house projects that had to be bumped to the head of the line.

But finally things got back on track this last week and I was able to make some progress. (warning, lots of pics)

First things first, here is the first floor board and one of the containers that will go into the pantry drawer.

And here we go with putting things together, from a clean floor to the first test box:

Next on the list is carpet, cutting an access panel in the center of the floor, and another for the jack storage area. The carpet should be thick enough to sit flush with the carriage bolt heads and deaden any squeaks that might show up in the future.

When looking at picture 4, it occurred to me that if I ditched the sliding tray altogether, I could easily fit a water tank in that hollow space... maybe 22 gallons or so. It would go a long way toward lowering my center of gravity, too. Meh, another project for another day.

As you can see from the test box in the last pic, the floor is short enough to allow me to remove the cargo boxes and carry passengers from time to time. That's very helpful when the in-laws are in town for a Mariners game. The box is long enough to carry a few MaxTrax and my dog's sliding ramp. I'm still in the process of sussing that out while I wait for slide hardware anyway, but I wanted to start one box at least.

We took it for a test drive and everything was so well secured that we couldn't hear a single squeak or rattle and the dog fell asleep like it was his second home. I'm really happy with how this prototype is turning out.

Next weekend, RTT!
 
Are you going to use wood in your final solution?
No, probably not. But wood is cheap and I can make plenty of mistakes without hurting my bank account too badly while fleshing out the design. Matching the curves of the interior walls and shaping the wood was a major pain. The end product will probably be a composite material, using the wood pieces as a template.
 
Mike, I like your platform. Did you ever think of buying a pre built unit to go on your platform? There was a post here the other day with a unit a guy bought from LL bean. Looked sorta like what you were going for. I know weight is the enemy when building something for a vehicle.

The best part of this platform frame design is that someone could do exactly that with just the frame and the floor pieces.

Once you get this in place, how you use the space is pretty much personal preference.

I thought about it and ruled it out early on because I will be filling the area with a bunch of oddly shaped stuff. The biggest problem with the two big drawers, for me, is the lack of flexibility. I want the freedom to change things as my needs change (or as my bright ideas fail in a "real world" application) and having a prefabbed box prevents that for the most part. But if someone wanted to buy a frame and floorboards, they could easily put something like the cargo caddy back there. Or some of the other options like Truck Vault, etc. And since the frame is steel and bolted directly into the floor, it's far more secure than just using turnbuckles on the stock chrome loops.
 
Mike, I know you have a hi-lift jack, but for those that don't - beware of blocking your jack access door...

BTW, did you take yours out when you got your hi-lift? Do you jack your truck up by the sliders?

I'm cutting a couple of access panels, one for the jack area. They'll be hinged or otherwise removable to allow access to the panel. The other will be in the center, to facilitate access to the nuts that are currently holding the floor boards in place.

I leave mine in there. They are near bullet proof and you never know when have a small jack might come in handy. I'll be getting an adapter for the Hi-Lift that works on all round tubes but I've got other things on the list with a higher priority.
