As i was all exited yesterday to connect my new toad for a possible trip today, all that excitement was gone as I realize my 7 pin plug behind the MH is not working. I remember last trip as I was getting home at night and the lights on the dolly (towing a FWD prior toad) went completely dark. I thought it was the dolly. I know my truck (new toad) is working properly. However when connected to the MH, not a single light.
Is there a fuse that need to look for? Or just need to disassemble the 7 pin conector and troubleshoot?

I had the same issue, 7 pin connector not working right and it was a blown fuse in the service bay. Not sure why it would be blown as I was the first owner.
There was a removable cap on the backside of the 7 pin trailer socket on our 2016 that would get knocked off by the mudflap under certain conditions. I relocated the socket to prevent that from happening. When at the chassis weld shop I noticed several chassis had them knocked off during loading on the truck for transport. I don't know if this has changed since 2016 but I would look at the backside of your socket to see if you have any issues.
Problem solved!!!!! Thanks to all. As it turns out I had 2 blown fuses on the back passenger battery compartment. Specifically to the trailer connections. All light working now!
