7. Even though we have a longbed truck, we opted to build a swing-out tire carrier for the Sled so the bed is kept clear of clutter when truck camping. EMS also offered these weld-in spindle kits with bearings and latches for the build-it-yourselfer. We tied the spindles in at the top of the bumper and underneath so it was mounted strong enough to support a spare 37-inch tire. Be careful to protect the spindle from weld spatter.
