Thanks for the link, this unit does have the A/C with a heat strip, how does the heat strip heat the trailer??
I had a 17' Boler
with a rooftop AC/heat strip combination. You have to camp at sites with electrical
hookup to use these because the heatstrip is just another word for electric heater(110 V), and of course the AC will require at least a 15A outlet. It probably has a fan to distribute the warm air. The advantage is your using the campgrounds power to heat with. A 1500W micro furnace(small cube type)will heat most 13' trailers easily.If you use a propane
furnace on the other hand and have a good battery
you should be able to heat the trailer without electrical
hookup but you use your propane
. Many people have used their trailers as emergency shelters(eg fires or mudslides in California) recently and having a propane
furnace could be pretty convenient in cool weather.
