I'm eyeing the RS rolling backpack (as compared to others I've seen) primarily because of the European airline carry-on sizing. Has anyone figured out a way to use a hip belt with it? (There don't seem to be any hooks or loops near the bottom.) Or have you found an alternative carry-on sized rolling backpack with a hip belt?
(Do to a medical condition I cannot carry more than about 5 pounds safely using just shoulder straps - but with the weight shifted to a hip belt, 20 pounds is a cinch. I also cannot carry more than about 10 pounds using my arms (so hauling a suitcase up multiple flights of stairs is a no-go). I want something I can use as a roller when practical, and as a backpack (with hipbelt!) when necessary...)
