Congratulations, Bruce. Well done. That's a "go anywhere" boat that will serve you well moving and at dock. I think your wife should get you a Fein Multi-master and a 55 gallon drum of Epifanes for Christmas.
Consider the Webasto diesel heater. They are just as good as the Espar but are considerably cheaper and use non-proprietary parts, according to Peter Tielen at Holland Marine here in Toronto.
