I saw this system at the Motorhome and Caravan Show. It looks good it was pretty expensive in the show £2100 but I’ve seen it since at under £1500. This makes it competitive to the Truma system. For me the advantages of Eberspacher is that most of it is under the van. The main criticism of this product is the noise, hopefully with it being located outside it will make it quiet to run. I like the idea that it runs off the diesel, but that is one of my main concerns also. How to fit the fuel line into the tank. The sprinter has an auxiliary tap fitted to the fuel tank, I have a Peugeot Boxer, and I hope someone can tell me if it has such a tap? Any comments about this system would be welcome, I have to make a decision in the next few days between it and the Truma. Any advice is welcome.
