How much weight are people putting on their tour pack racks? My rack has a label saying 5 lb limit. I weighed my empty Rickrack bag that I have for my tri-glide and it weighed 9.7 lbs. I like the no strap hook up of the Rickrack but I'd like to be sure it won't harm my Roadmaster tour pack as it would probably get close to 30lbs. loaded.
