Where to locate a Range extender for TST 507 tire pressure monitor

We have the TST 507 system on our BC 3650RL, and it will occasionally drop the sensor on a tire while we are traveling. It does pick it back up eventually (10-15 minutes down the road), but purchased the range extender to boost the signal. Has anyone out there added this booster and where did you mount it? I thought of putting it in the front basement bay and tapping into the 12 volt wiring there, but wondered about putting it up in the wardrobe in the bedroom using the 12 volt power from the TV booster. Any suggestions?

I put mine in front compartment on level up bracket and got power from compartment light. I added a toggle switch and it turns on range extender and observation camera with one switch. Floyd

Here is what I did with mine. I taped it into the junction box and put a swoith and a fuse in to protect it.

I put ours on the front of pinbox and wired it into the taillights at the 7 pin connector box.

I put ours in the front generator storage compartment. Tapped into the power from the compartment light.
