Hey Mike, in order to replace the Advent Analog Wall Thermostat ACTH11 you'll need the Air Distribution Box w/ Wall-Mounted Thermostat for Advent Air RV Air Conditioners part # ACRG15. This is a digital style replacement which is what you'll need since the older style is discontinued. This also means a new air distribution box is needed which comes with the kit I mentioned. We don't have an install video but I did attach a link to detailed instructions for this kit. Check those out on this page down below and let me know what you think.

So currently I have the ACTH11 thermostat that’s going crazy. I want to replace with the replacement part and trim kit. So this is compatible with going from the 8 wire setup I currently have? (Freeze stat, (3) fan speeds, Furnace tigger, 12v, Ground, and AC)?
