TireMinder Booster Installation Location

I have been wondering about getting a TPM setup for the TH, and not sure wither to get the booster or if I would even need it considering the axles are mid ship. I was thinking the cab of the truck could reduce the signal, but had not thought about the sender batteries being less than 100% becoming an issue.

So with a couple good suggestions to mounting for the booster, why not just go ahead and add that to be sure all the time?

Anybody care to add if they believe mounting the booster closer to the axles would be better than in the pin box?
