How to make RV heaters at Truma

We were invited to Truma. The company most well-known for caravan heaters. We travelled to Munich with a lot of questions on our minds. We didn't know that we were about to see much more than we thought was possible. We'll visit the heater production lines in this first episode of our journey. http://www.caravanuutiset.com # Tilaa kanava http://www.youtube.com/subscription_center?add_user=Caravanuutiset # Facebook http://www.facebook.com/Caravanuutiset # Google+ http://plus.google.com/b/106203196099134005520/
