I was planning on doing the rear heater thing with a hydrodronic espar too but the rear van fan is not very efficient. Apparently there’s a really low power sucking fan blower motor that comes in certain years of Durango’s, but we got redirected when some lazy pos nurse ruined my wife’s left foot. Now if we ever get on our feet again I’m thinking about doing a heated floor with the espar unit. Might be the only way I can get my wife out in the winter months again.
