I need help

Just purchased a 2021 r-pod 196. We bought this camper 1200 miles away from where we live mainly because no one around us had any. I have no 12 volt power at all. Battery is great. I metered it at 12.8v. My awning works as well as my power hitch. Other than that,no 112 v power . When shore power is connected, everything works great and battery shows full charge in display. It’s under warranty but I feel like my local dealer(100 miles away) is gonna give me a problem. I have also checked the busman fuse under the camper and have 12volts on both posts so I’m pretty sure that’s working. Any ideas are greatly appreciated.

The fuses are all "mini" fuses and have a little window that allows you to actually see the fusible link inside. Without tools, you can just pull one out, turn it sideways and see if the link is broken or not.

If you're good with a multimeter, you can "sometimes" measure the voltage on both sides of the fuse. If the voltages are the same at both ends of the fuse; it's working. This is not always possible though, as often the connectors are not always reachable.
