......1.0 go to all electric heat..put a small electric heater wherever you need the heat and stow the heaters while traveling....duct work looses heat or in case of A/C picks up heat usually because of bad insulation/leakage.....I'd stay away from duct work if I could by using fans and portable unites where ever posssible...A/C is best if used on top of coach-takeing heat off the ceiling cooling it down and dropping the cold air on the passsengers if possible....again use a portable fan it move the air around.....2.0 If you just got to use propane or LNG to heat-put the heating unite at the lowest point of the coach...take cold air off the floor-heat it and blow it on to passengers....If you have an under coach A/C unite you have to take heat off the ceiling suck it down to the cooling unite and pump it back up on the passengers....if you can avoid ducts by using fans-use them!....cheaper -better-faster-better coverage.....moving air causes you to feel 6 degrees cooler because of evaporation from the skin...geofkaye
