Installed the 2KW version in my slide in truck camper. No issues on shipping or missing parts. Easy install after some planning and plenty of info out there on that thing called the inter-web! Mine did come with a metal fuel tank which I initially liked. Decided not to go with it as I like seeing how much fuel is available. I also upgraded to a NAPA diesel inline fuel filter.Tried the unit out on a cold soggy trip to the Oregon Coast. Heater worked like a champ. Sips fuel, power and due to installation almost no noise. On top of all that has a very nice heat to boot. This thing is much better than the OEM furnace.A good upgrade and no regrets. For the price it can't be beat. The only question that remains is.......longevity.
