My Forester motorhome did not come with a TPMS system. But ever since I installed a tire pressure monitoring system, or TPMS as it is often referred to, on my first coach I was sold. A good system is not cheap but the safety factor alone is worth the investment. TPMS will warn you when a tire starts to get low on air pressure. A low tire will lead to a blowout if not corrected. Running tires with pressures too low will ruin the tires quickly. TPMS warns you. I carry an
onboard Viair air compressor to add air anywhere, if my TPMS tells me I need air. I went with a
Dill Air Internal sensor system, much like what comes as standard equipment on most new cars, and also includes a separate monitor display which reads each tire's pressure and warns you when it falls below a preset minimum or exceeds the safe maximum. I also had Les Schwab install solid one piece brass valves custom designed for the Ford E-450 from
Duallyvalve.com to minimize leak problems. I highly recommend this setup.
