Many moons ago I was hunting for a manual in PDF format for our 2007 Diplomat. I thought that Monaco would provide this on their website as a natural part of their customer service, but that is not the case.
Being back in Denmark for a short time, I this time brought the manual with me to my office and spend just 25 minutes at our printer/scanner, and as a result of this, you can now download the manual on my web site.
2007 Diplomat manual
I have also included a 12V chassis wiring diagram provided to me earlier from my fellow IRV2er Robin_M
I hope and trust that some of you will find this useful.
