That's not a bad looking rack for the money. The attached photo shows how I packed for my "lap". The roll across the back seat is an Anydy Strapz Gear Sacz and contains my self inflate mattress and sleeping bag. It did restrict my rear vision a bit, but nothing to get excited about. Right pannier holds a two man tent and footware. Left pannier holds clothes, toiletries, first aid, waterproof overgear. Top box has food and a cask of red, cooking gear, water, maps and other assorted junk.
Worked beautifully for me!
My "Grey Nomad" spies say that around April is the best time to head north.
