Question:

Good Afternoon. We have a Salem Hemisphere 40foot 5th wheel. Looking to put a TPMS on the trailer and our 2019 GMC Denali 3500 dually. Which system do you recommend is the best for this situation. The Tire minder A1AS or the TST system. I am having a hard time trying to learn which is the best system for my $ Thanks for your time

Personally, I would go with the TireMinder A1AS TPMS # TM79FR. There are a couple reasons for this. One being that the TST TPMS for RVs # TST-507-FT-6-C (or any other TST system) would require you to purchase 4 additional sensors # TST-507-FT-S2 (x2) because your 2019 GMC Sierra 3500 is a dually. While the TireMinder A1AS TPMS # TM79FR comes with 10 sensors, which is enough to cover all 6 tires on your 3500 and the 4 on your Salem Hemisphere 5th wheel.

The TireMinder A1AS TPMS # TM79FR (every 6 seconds) also refreshes twice as often as the TST TPMS for RVs # TST-507-FT-6-C (every 12 seconds). I also like that the TireMinder A1AS TPMS # TM79FR has the option to utilize your smartphone as the monitor if you would prefer to not have another screen in the cab of your truck, but still provides the monitor if you would prefer that option.

Either option will provide you with a way to monitor the tire pressure and temperature, but the additional versatility and not needing to purchase additional sensors makes me lean towards the TireMinder A1AS TPMS # TM79FR as the best system for your money.
