Question:
Hi I am looking for a roof mount A/c and heat pump for a cargo trailer I have a 20foot cargo with a skylight that I am looking to add the unit I was looking at DMC26ZR but in the video it stated not approved for cargo trailer. Do you have one that is. I am little concerned about the ones with “heat strip” that it may not keep up in Massachusetts. Ultimately looking to turn a cargo trailer into an office. Thank you Steve

Hey Steve, thanks for reaching out. The Dometic # DMC26ZR is not approved for cargo trailers because of the roof strength and thickness. Most cargo trailers do not have a reenforced roof structure capable of supporting an AC unit (around 80 lbs). AC units can be added to cargo trailers but in most cases your would need to build out and reenforce the roof. Also if you were to install an AC unit that is not approved for a cargo trailer it will void your warranty.
All that being said, we do offer an AC unit that is approved for a cargo trailer, the Furrion Chill HE, which you can get in either White or Black:
- White: Furrion Chill HE RV Air Conditioner System # FR55PV
- Black: Furrion Chill HE RV Air Conditioner System # FR23PV
Just keep in mind the roof of your trailer must be between 3-1/2" to 6" thick to install the AC so you most likely will need to build out the roof to make it fit.
There is a heat strip add-on for the Furrion Ac unit part # FR63PR. Full honesty though, this heat strip will not keep your camper warm during the Massachusetts winter. It might raise the temperature inside the camper by a couple degrees, but the heat strip serves more to just take the chill out of the air and is not a replacement for a real furnace. So it will help to take the bite out of the air on those chilly mornings, but if you will be working in the trailer full time during the winter you will probably want to look into an alternative heat source.
