I wired mine into the front storage in the 5th wheel. TST has a simple set of instructions for clamping it to the battery, which I found unacceptable. I screwed it to the bulkhead wall (wood) and wired it permanently into the power supply for a nearby interior storage light, with an in-line on-off switch and fuse. I would not put it in the truck. Although the repeater has better antennae than the receiver, it just seems like better sense to mount it about half way between the receiver and the 5th wheel sensors .
