Heat? You want to talk heat? The heat as of late has nearly killed me... :(
Curious what the Springdale has for an arctic package? Thicker walls, better insulation in ceiling or?
Our 29' KZ TT has standard insulation and 30 amp service. I installed 3 permanent recessed electric heaters totalling 2,000 watts and never use the furnace anymore (4 seasons now). We've camped all the way through the fall and even into Dec. The heating does struggle by the time it gets down to freezing tho. and need to wear thick socks and/or slippers or shoes. The floor gets cold due to lack of heat under it and the air inside stratifies. Temps have dipped a bit below freezing and been fine. The only thing that will freeze is the water hose out to the pedestal. For a couple of degrees below freezing or so, there's enough heat radiating into the floor to protect piping and tanks. This heating setup keeps the TT toasty warm and evenly heated end to end.
If your insulation is truly better than standard, 1500 - 2,000 watts should work fine. But... In cold weather you need to exhaust moisture laden air out or use a dehumidifier. If you don't, moisture will migrate through the walls and ceiling where it will condense on the cold exterior skin and lead to rot & mold. In our TT, I sealed up all the holes in the floor. If you seal up every crack & hole to retain heat and not remove the moisture, you
will have issues if you camp often enough in cold weather. I would look at using a dehumidifier if you want to camp more than the occasional weekend in cold weather.
These photos show the heaters I installed. Two recessed King pic-a-watt (adjustable setting) fan forced (axial blades) heaters and in the kitchen/living area, a 1,000 watt kick space heater. The kick space heater is the same width as the stove and all I had to do was remove the blank panel that was there. I installed a low voltage thermostat in each room/area but line voltage would work too. I built my own demand controller so that when a toaster, coffee maker, hair dryer or other appliance is plugged in, the heaters are automatically temporarily shut off. Could be done with a manual switch if you don't forget to turn the heaters off and back on.
Running wires concealed through the ceiling, interior walls, behind the shower, etc. was relatively straightforward but time consuming. Best mod I've ever done in a TT. It's VERY quiet too. Too bad it's not offered as an option by a TT manufacturer.
For reasons I don't want to get into, I wouldn't go with Cheapheat.
