Bed Rack Mod: Under Rack Table Mount

[GladiG8R]

I need the engineering genius of the overland/expedition community to solve a dilemma. Front Runner makes an under rack table mount for their roof racks. I want to do something similar with my RCI bed rack (and I don't want to pay FR prices). Here's the question, what can I fabricate that would do the same thing? The budget is $100. The table is a Rubbermaid folding table and the flat folded dimensions are 27"W x 30"L x 2.5"H. The bed rack has slots for carriage bolts so you can pretty much bolt anything on.

Thank you for any help you can provide.

Also, if this has been done, just let me know what to search as I have exhausted my ideas on keywords that might drum up a result.

Why couldn't you just use 2 pieces of 2.75" C channel and bolt it to your rack?

I've not seen 2.75" C-channel, but this is generally the direction I would consider. You could always use 3" channel and add shims. I've built a few different sliding racks this way.

I did my first solar panel slide-out rack with C-channel:


The panel slides in/out of this frame, which is hinged at the bottom of the photo to capture the panel:


My new solar panel rack is similar, except it's angle-stock for the sides and C-channel for the short-ends. I laminated some plastic sliders and stacked up shims to get the channel to match the 1.4" thickness of the panel:




Lastly, I'm doing a similar camp-table mount that fits under my solar panel by using C-channel just to capture the "ends" of the table. The table fits between aluminum risers (to corral it left/right) and the channel holds it fore/aft.



This is the prototype with 3" x 1/2" C-Channel, just to prove it'll work. It's fairly solid, but I will replace with 3" x 1" C-channel to get a slightly better grip on the table once my metal supplier is open for walk-in business again:



I use the same hinged panel to capture the solar panel (top) and the table (bottom), so that I can lock both into the rack with a single padlock hasp.
