Ragen FS2500 electrical issues

[Woodro]

Hello, new member here! Have a Ragen, 2007, FS2500. It's been a great trailer overall. However, I have always suspected electrical issues from day 1. the biggest problem is that it eats batteries. Camping World replaced the converter last year, and told me all my problems were solved..... NOT. It just ate another battery (Interstate). So I replaced with another battery (used but good, from my boat), charged it, and went camping. It lasted about 4 hours with everything running. I hooked up to shore power and everything was fine. When we started packing up, the beds would not raise. After checking all the fuses, and breakers I could not find anything bad, but I did notice that all the outdoor lights were also not working. RV shop jumped the pull switch up front and everything works. I am hoping that I finally have an obvious sign of what is really going on. Anybody had any similar issues?

Thanks,
Woodro
