Agreed on the height addition -- I actually wanted this, for height/hatch/door reasons, but yeah, it's a concern if you don't want that height. Don't think it adds that much to the weight, though. The floor is 50-60lbs with 1/4 ply on top and bottom, yes, but without the sandwich method, most people go with 1/2 ply, which is nearly as heavy. You're really only looking at an addition of 10-15 pounds, I would think.
