Are you MACHing my words?
Yeah I saw the spelling error in my subsequent research. Thanks for the correction.
Looks like I will have to get on the roof again and remove the cover to see exactly which model I have and if it is equipped as you stated. Just normal trailer owning stuff. Always a challenge.
Thanks

Update: Found the brochure for my 5er. It shows the standard AC as 15K and the bedroom unit (optional) as 13.5K. Mach III or 5 with "power saver" is still to determined.
