With the Grech Strada RV not really being that large you can just mount the repeater for the TST TPMS Internal Tire Sensors # TST-507-INT-6-C somewhere in the engine bay. A couple of self-tapping screws will easily mount this to an open space. I've attached an example of this below that we do quite often with a battery disconnect switch.

If you were using these sensors on a trailer then I'd say it'd be best to try and get it as close to the end of the RV as possible to get the best connectivity, but it has more than enough range for the length of the RV. Placing the repeater inside the engine bay will also help protect it from the elements and road debris so it'll have a longer lifespan and much easier installation since you'll be close to the battery.

Hello. Will this repeater will still draw power with key off?

@Ray it does draw power but will enter sleep mode when there is no activity. It is possible to install this on the running light circuit so it will only have power with the running lights and won't be able to drain the battery if you're worried about it.
