AC replacement crosswalk to new mode numbers?

[first5thwheel]

Does anyone in the forum know of a website or link to replace my old Coleman AC unit? The model number that I have does not crosswalk to a replacement, or at least I am having trouble finding a replacement that will work in place of my factory unit.
I have the Coleman 8333A8664 and it is the type that is ducted throughout the cabin. I think it is 16K BTU but not sure. It is the Flush mount ceiling type with just the intake grill in the ceiling and it has a mounted wall AC thermostat control that my Propane furnace shares.
Any suggestions where I can find a replacement that will work as I am sure the old part number is outdated (the year 2000)
My rig is a 2000 Fleetwood Wilderness.

Have you called Coleman?

Thank you Wingnut, just got off the phone with Coleman: And if any of you need the number for Coleman RV Air conditioners the number is: 316-832-4357 (Central Time Zone) and they cross-referenced my old part number of: 8333A8664 to that of 48204C876 which is the Coleman Mach 15 - 15,000 BTU. The smaller size will fit as well Coleman Mach 13 - 13,000 BTU part number 48203B876. PPL as well sells them and the number cross-references to their part number which is 63140. For those of you who did not know this such as myself: The upper roof unit is referred to as the "dummy unit" that plugs into a harness on the rooftop that will correspond to your controls inside the rig. I was given a quote @ PPL of $574.95 and that price was as of today: 4-2-12. Hopefully this post may help someone else who is trying to cross reference their older Coleman’s from 2000.
