Well I think it's time to put in a diesel heater and remove the propane heater. Looking at a Espar D2 heater. Looked at Snuggers and Planners and just not sure I want to go that route. Espar fully loaded with sea fittings $1200 with 2 year warranty. Trying to decide where to put it. How big of a fuel tank Id need. How many vents I want and where to put them. Any advise as to what heater to buy? Good idea? Waste of money?
