Question:

Same question, different product. My customer has a 25 year old Coleman 7300 series 13,000 BTU AC, will this Advent ACCOL135 be plug and play with a Coleman this old?

Possibly leaning more towards no. The issue we've discovered in the last 18 months is the adapter included with the Advent Air Replacement RV Air Conditioner for Coleman Setup item # ACCOL135 does not match up the pin functions on the air boxes. So you'll have to rewire the adapter cable if you encounter this issue.

Our solution has been to replace the older AC systems with all new components like the Advent Air Low Profile RV Air Conditioner System item # ADV45SR.

Hey, did you decide to rewire the adapter cable or go with replacing the older AC system with the new Advent Air system? I'm asking because your experience could help others facing similar issues with older Coleman units.
