My partner and I have been travelling Australia in our fourby and caravan for the last 2.5 years, we’ve tackled some of the toughest roads around, we should have picked up this tyre pressure monitor earlier, it’s solar powered and sits on the dash giving real time feedback and piece of mind that your not missing any slow leaks as your driving along, we are always recommending this to other travelers we meet. Anything that offers abit more safety while driving out bush is always a good thing
