Don't strap your luggage in. Snap it in place and forget about it. The packout plate from RackUp Trailers allows you to use the Milwaukee versatile storage system.
 
The Milwaukee Mounting Plate is constructed using US steel, giving you up to a 200lbs weight capacity when mounted to the floor and 100lbs when mounted to walls. Twice that of the plastic version.
