The biggest issue you're going to run into with the Tacoma is getting the shell to seal, it's a PITA even just getting the shell alone mounted because of the stupid plastic bed and funky bed caps. Certainly doable and some folks on Tacomaworld have done it using brackets that attched to the inside tracks, but you're going to have to pay extra attention to the seals. If you're trying to keep the dust out you'll need to do a bit more work including taping the seams, dealing with the cubbies and adding a tailgate seal. Recheck the clamps periodically, don't get crazy on them but make sure they stay snug.
