Dunno how your interior is, but mine is already (2 weeks into having it) getting beyond cluttered with gadgets.....cell phone holder, Tom-Tom, Bluetooth handfree, Wireless MP3 transmitter, MP3 player charger, a couple of remotes for stereo components (yeh, remotes in a standard cab pickup <grin>)....I have flown simpler aircraft :icon_biggrin: Add to that an appalling lack of storage compartments in a standard cab :icon_cry:
So, my next project is to build a custom console out of sheet metal, PVC pipe and fiberglass, covered with upholstery for a decent interior match. It will have at least a dozen hidden plug-in power sockets, places/spots for all the gizmos, a couple extra cupholders, and run between the front of the seat and the console on the lower portion, then arch up and have an urmrest section on the seat, with hinged lid, cupholders, and specific orginizer compartments so I am not digging thru one big pile of junk to find a pen or a lighter when I need one.
The basic shell/frame will be pop-riveted and welded sheet metal (AKA known as common duct work sheet, dirt cheap) and the curved edges/corners will be a mix of PVC and resin-impregnated cardboard tube, riveted in place. The whole thing will be covered in 1/4" of upholstory foam with glass smoothing in any needed areas, then a mix of carpet and vynal for a covering. (If you are not comfortable with metalwork, 1/4" plywood wiould work just as well)
I have done similar project to some of my cars in the past, and the advantage of mixed materials over straight fiberglass is lower cost, and there is no need for a mold as the entire thing is self-supporting as it is built. The disadvantages are weight (its a ton heavier than straight glass) and it does tend to look like crap internally--but that is hidden and nobody ever sees it anyway.
