Inspired by Jim Dodd in post #11 I went down to the metal shop and purchased some steel, my son cut it up with his chop saw and welded it up, then I spent a day painting, drilling and mounting.
Total cost, $60 for the steel, $40 for SS hardware and some quaility drill bits to drill the mounting holes, some left over canvas and a couple spare 2x3's
Thanks Jim Dodd for posting that picture, really inspired me to ditch the cap and go topless. My days of commando camping in the North Bay, Ontario Walmart or along the side of highway 11 in northern Ontario under the cap are over.
The new style Tacoma plastic bed created some issues, the racks can come off but the amount of time it will take to remove/replace them makes this system pretty much a year round attachment.
The rear rack could have been a skosh lower, my 15' Chum with curved ends came close to the cab roof, so I mounted the cross member 2x3 to the back of the upright rather than the top. The bolt holes are the same and the cross bar can be easily moved to the top if I end up finding a real 16' Chestnut Prospector some day.
