I replaced the AC yesterday with a Coleman Mach 8. Wow, what a difference. Blows harder and colder than old unit ever did! I'm taking the old unit to Holiday World, where I purchased the trailer(AC still under warrantee ). I have a 1990s 7500 btu AC as a second unit on the trailer that I will swap out with the new replacement. Woooo them boogers weren't easy for a 45 year old fat man to lug up and down that step ladder.
