Good Morning Dave,
According to Dometic's online Customer Support Center, the Cool Cat DuoTherm is still available. Here are some responses:
"Yes they still make this particular model. I have provided a manual for you to take a look at. I believe there is a heat pump model as well as a standard AC model. Let us know if you have any more questions."
"You can not purchase a complete product directly from Dometic. If this unit is not stocked at Camping World they should be able to order it in for you or you can contact another dealer in your area to purchase this from. We do not have access to the dealers inventory however if they do not stock this product they can order it. To locate a dealer near you please go to Welcome to eDometic and use the dealer/service center locator tool. Thank you
I have not since the last reply called my dealers, but I know that Camping World does not show it on their website. I plan to go to a local dealer to see if they can order it for me and check pricing. Seems the perfect solution for just what we need...no overhead clearance problems and original look. Thanks! I will let you know if I hear anything else.
