Keystone doesn't offer the "heat strip option" from the factory, but any RV dealership can install the A/C manufacturer's OEM heat strip in any air conditioner unit that is wired/equipped to accept it. That's likely what the salesman was relaying to you. The heat strip is available for your model, it's a "dealer installed item" and he can have it installed at the dealership for you (if you want it) for $79. On some brands of Keystone trailers, it is installed as OEM, on Passports, it's not available from the factory, although you may find an occasional Passport that was built when Keystone ran out of air conditioners at the assembly plant and "borrowed some" from the Alpine line or from the Fuzion line, where all their rear air conditioners come equipped with a heat strip (that's usually not properly connected)….. So, finding one in a Passport is not impossible, but it's not included in the typical build or as a factory installed option.

If it were me, I'd opt to have the heat strip installed. While it's true that it's only about the "heat output" of a small electric heater, many times that's all you need to run to "take the chill off" the RV. And, if you have pets or small children, there's very little space in any "small RV" to operate a "hot cube" that doesn't present an issue with children or pets accidentally bumping into it or it being in the way if you place it on a kitchen counter....

Realize that 1200-1500 watts is only about 5000 BTU's of heat, but that's normally all you need when the temperature is below comfortable, but not below freezing.

As stated, the A/C heat strip is not a "feel immediate warmth" kind of device because of the volume of air that flows over the small heating element, but when used overnight, the A/C fan produces the "white noise" which helps with outside distractions in a busy RV park while there "just enough heat" to keep the RV warm inside without using propane.

We've had one on most of our RV's, this A/C doesn't have the connections to install one and we do miss it, although we've got a small electric heater that we use and place "in the way, on the galley counter"....
