Irwin Citation 39.9 Port Aransas
Hi,

I just bought a 1979 Irwin Citation 39 that has passive refrigeration. The box is 8.29 cu ft. I've narrowed it down to the Isotherm 2017 or 2013 versus the Dometic CS-NC-15 DIY kit.

I'm worried that the Isotherm will be difficult to install and that the Dometic won't be powerful enough to keep an 8.26 cu ft box cool without excessive battery consumption. I am looking to hear from people who have experience with an icebox this large and these particular units.

Thanks
Aaron

I do not know about the particular units but I have a Citation 40. Basically the same hull and deck with a different interior. I will mention I found when installing a light in my box that the insulation was almost non existent in mine. They used poured foam but not enough and there were large air spaces near the top. I had to add more foam insulation. No matter what unit you use check to make sure the insulation is complete. Good luck with the project.
