I just got mine. I'm very impressed with the quality, etc. I'm wondering about the weight to put on the lid though. I know I've heard everything from "The luggage rack is just for looks" to "I've put 30Kmi on with 20lbs. on the lid" (paraphrased, of course). I don't have the owner's manual with me so.... How much weight is the lid rated for? What has everyone's experience been with putting things on top of the trunk?
