Bought this diesel heater for my self-converted Sprinter Van after using a Little Buddy heater intermittently for a couple of years, and not being ready to spend at least $600 on an Espar or Webasto.Heater did not have a silencer included, and the rubber fuel line used for joining the PVC fuel line was much too tight to easily fit one into the other, so I purchased some at an auto parts store that was easier to work with, and ordered a separate silencer online as well. The instructions included with the heater were pretty worthless, but there are plenty of youtube install videos online.Overall, and especially for the price, I am very happy with my purchase. Even if the heater breaks down in a year or two, it is still less expensive than the alternative, and for us, it has been putting out plenty of heat at a very low rate of fuel usage and electrical draw.
