KC, I've thought about tire monitors before, but never bit.  There are many brands out there now.  I think there was an article this summer or fall in FMC or Motorhome magazine covering most of them.  Some have replaceable batteries, some you buy entire tips.  $$$ in addition to initial outlay.  Obviously from comments here so far, I have to question reliability.  I opt to just watch the tires, all 10, at every stop or rest area, at least visually if not with my infrared thermosensor "gun".
Henderson's just installed a Safe-T-Plus stabilizer, like on our old Pace Arrow, and I'll have more control in any blowout, as well as in wind, ruts, etc.  New tire's, shocks, and 8 motion control air valves should help.
They found one cracked air line connection last week and replaced it, but overnight the red needle (secondary tank) still goes to 0, so they'll check again.  But that was unscheduled and they are busy, so don't know when they'll get to it... air leaks are a bear to track down.  At this rate, we may still be here when you arrive.  We were supposed to be outa here today, now that the K&N engine air filter arrived.
