Even pickup trucks don't have 12 VDC at the hitch plug from the factory. Most are wired to the fuse box, but you gotta put the fuse in to make it hot. Unfortunately, most Thors don't have it prewired to the fuse box. If you are lucky, there may be a wire in the bundle, but you will need to trace it to the other end and make it hot yourself.
