First off, let me explain Chinese Diesel Heaters. The Chinese blatantly copied the original European Cabin heaters and made these bad boys.They_e even BETTER and they cost a fraction of the price. Even if one of these broke every couple months I could replace it and heat for two years and still not have pay the full price of a Webasto.Do your research on YouTube to make sure you can handle the install, and make the best purchase of your life. Warm, dry, cheap air!
