* Storage is my Achilles' heel... I'm never happy with what I've got, or where it's stored. This time, my project is on my tow vehicle, not the 4x8 trailer.
* I've previously posted about my compartmentalized truck bed storage scheme
http://www.tnttt.com/viewtopic.php?f=2&t=68912&hilit=+compartment#p1210246, which works OK, but since I now leave my gear and tools in the exposed bed in the uncovered driveway, year-round (tired of loading and unloading it), I have to cover the bed to limit the leaves and debris accumulating there; it's always parked beneath two huge oak trees, and the amount of leaves and oak pollen it can collect is staggering. I've been using a 6x8 tarp for the last year, and while it does the covering job well, it looks too "redneck" and unsightly for my wife, and we seldom use the '04 Chevy Silverado 2500HD anymore, between my camping trips. It has the least # of miles of any of our four vehicles, and is in top condition, so I'd like to use it more often around town...so I'll make a semi-hidden bed-cover that will not shame my wife anymore.

*I just can't bring myself to purchase a factory-built cover, even a velcro-attachment type for $150, while the hard-cover types I like cost up to $1500. Plus, I won't remove my big cross-over toolbox to fit one in (no cover I saw exactly matches the size, and the alterations I must make to fit one in, with the truck crane that I'm keeping in the bed, too). I've envisioned a two-piece plywood cover that will sit in a channel just under the bed rail height, mostly hidden from view. I'll paint it black, like my truck box, and it will leave room for bull-ring attachment points on the rails, so I can still haul items strapped on top of the plywood covers. Larger, heavy items that need to be hauled will fit into my wife's highly modified-for-towing '98 GMC Sierra.

* I'm collecting the parts now, and only need the plywood, poly, and paint to start on it. I've been considering doing this for six months now, and am finally going to do it. I'm using the 12-gauge Superstrut from Home Depot, which will be mounted about an inch or so below rail height, all the way forward under an overhanging lip on the crossover toolbox. I'll mount the left channel first, before inserting the panels into the slot, then put the second channel over the opposite edges, and lower it down into position to insert the second set of carriage bolts into the holes already existing on the right side bed rail. I'll probably need a handle on each panel to help me slide them over each other, since together they're thicker than the slot they go in (there should be some give, and eventually they'll wear-in a groove to enable easier movement...better than too loose a fit to start with).

* First of all, I have to lower the Hi-lift jack I mounted awhile back to the right bed wall; it sticks up an inch too high. And I'll have to mount an upward-facing roller caster near the center of the existing inner compartment structure, to support the center of the interface of the two panels. After that, the panels will be cut and poly'd & painted, similar to the way I coated the trailer (using 1/2 the # of coats, though). If it turns out OK, then it's a good project...if it turns out "redneck"-engineered-looking, then it'll be a perfect match for my 4x8 trailer. Win-win all-around. I'll probably spend about $100 on this project, which seems to fall under my wife's radar. Wish me luck!

EDIT, later same afternoon: I just had to test my preliminary measurements before it rains tonight, so I went to the truck and removed the tarp. I also removed the Hi-lift mounting bracket I made. Then, I sawed the Superstrut in half (5+5 feet) and mounted the left side as stated before. Good so far, but when I tried to stuff two pieces of scrap 15/32" plywood into the 7/8" slot, they wouldn't go. Even using a prybar and a BFH. So, everywhere I stated that I'd use a 15/32" thick panel, that's now downsized to 13/32". 13/32" x 2 = 26/32" which will fit into a 7/8"(or 28/32") slot. I should've bought the thinner 14 gauge Superstrut, but HD was out of them yesterday. Otherwise, it looks like my plan is feasible.

EDIT #2, four days later: revised plans, again downsizing the thickness of the plywood. Going to try 11/32" thick, because my Home Depot doesn't stock 13/32", nor does the Lowe's. Their 11/32" is sometimes listed as 3/8", which is better/thicker, but I know they stock the 11/32". With intermittent rain for the last few days popping up, I haven't gotten the wood, yet, nor has there been a window of opportunity to use "the mix" to waterproof it (outside in the driveway), nor to paint over it after the poly goes on. I figure that I need a whole afternoon of sun to manage the coating applications, then only another hour to install the pieces. It always rains when I need it to be dry, it seems, or conversely.
