I have a 2004 Monaco Diplomat and have a problem that I have never had before. While getting ready for a short 3 day trip, when I hooked up my shore line (I always plug into my house electric while getting ready for any trip.) I noticed that I was only getting 30a power. I thought that it must be something in my house receptacle. We were in a hurry to leave and I thought I would check the shore line at the RV campground when we got there. When we hooked up at the campground, we still only had 20 and 30a, but no 50amp. 30 amp is OK for most trips, but we need the full 50 amp power for long trips. You can't run both A/C on 30 amp. I called 2 different RV stores and neither one had a idea about how to fix it. I hope someone out there can give me some ideas. I think it could be the "DISTRIBUTION PANEL". Does that panel ever go bad? Any advice would be appreciated.
