We have the TST 507 non flow thru due to problems I heard that the flow thru have. It only takes a few seconds to remove the sensor with the tool to add air. The TPMS has been great for about 5k mi towing. Would recommend getting sensors for spare tires on TV and towed unit and think sensors for airbags is overkill. TST 507 can handle 22 tires if needed.
