Kia Sedona Modifications My Honda Element had a storage platform that spanned the full width of the vehicle's interior. Between that and the vacant spare-tire well, I was able to carry enough gear that I could camp in the car at any time. There were some drawbacks, though. For one thing, I had no rear seats, so could only carry one passenger. The other compromise was that in order to sleep inside, I had to remove the driver's seat storage armrest; push both front seats all the way forward; open the liftgate and tailgate; fold out the front and rear platform extensions; and install the Honda cabana. In cold weather I'd leave the tailgates closed and use only the front extension, which left me a bit cramped. The design aim for my 2014 Kia Sedona was to be able to keep both second-row seats in place, allowing me to carry three passengers, and only need to remove the second-row seat behind the driver (super easy) for sleeping. The way to do this without giving up my storage space was to remove the third-row seats, build a cover and access doors over the third-row seat storage well, and add a couple of topside storage bins, one of which could be removed quickly without tools. Gear Wells and Main (Rear) Storage Bin I don't have any construction photos of the rear-seat well cover, but suffice it to say that getting a frame in place to support it without having to drill holes in the underside of the car took some doing. I did manage to create a frame that used only existing anchors. Likewise I didn't document the construction of the main storage bin, but it was very straightforward, requiring only eight angle brackets to form the structure and four more brackets to secure it to the well cover. The main bin's installation is "permanent," but with an electric screwdriver the eight sheet metal screws securing the bin can be removed in just a few minutes.

Figure 3: Looking down into the main storage bin toward the secondary storage well hatch    Figure 4: Secondary storage well hatch open to reveal emergency gear Anchoring the Secondary (Front) Storage Bin In order to avoid drilling through the floor, I anchored an 18" x 20" x 3/4" piece of melamine board to the existing brackets for the third-row seats. To avoid bolt heads and nuts protruding up into the storage area, I fabricated wooden bucks to hold 1/4" carriage bolts that would protrude just enough into the board that I could use barrel nuts to hold the board down. Because the bolts would be too long to allow feeding the bucks into the seat anchor wells, I had to use cap nuts, which allowed me to adjust the height of the bolts once the bucks were seated in the anchor wells.

This prevents the plug for the inverter and auxiliary outlet from popping out of the socket and also offers some physical protection.
