Thule's 422 Xsporter ladder rack - $450

Thule's 422 Xsporter rack system mounts on the bed rails of your truck, and accommodates various Thule carriers and loads.
The rack's two load bars can be raised and lowered — great for loading and unloading bikes, short boards, or snow boards from your carrier.
Raise your cargo up, and you can use your truck bed for storing other items.
These are used but are in great condition.
I have locks that keep them locked to your truck bed.
The newer versions sell for over $1000
