I have a box on zega panniers, it's a bit of an experiment. if you're handy and can make up a simple strap bracket for the rear, it'll work, I don't have a box to fit it with. I can send you photos and details but I'm away from the shop at the overland expo in arizona, I can send you more details in a week when I get home
please send me email with your email address and I'll send email direct. thanks'
