Hi Tony,

Are the Coleman Mach 8's easy to obtain? I know of someone that can install them, but am looking to replace all 4 of them on my 2004 Marathon H3 D/S. The original units are still working, but during this past summer of extreme southern heat (June/July 2022) from TX to Alabama, they were really put to their test and began to fail (2 of 4) and not cool well. Decided to replace them. Will the new Mach 8's work in place of the 2004 units (that are not as low profile as the newer ones)? Thanks for the help, Mike
