We have a 2015 38RL, based on your description it sounds like you’ve lost 120VAC, and your power reel question would lead me to trace electrical power starting at the pole/plug. Power reels are a big source of power problems, it has to do with the contacts in the rotating spool. We’ve never had problems and some have fixed that by just rotating the reel. Then make sure you have 120v at the transfer switch in the battery compartment (where the power cord terminates. If you’ve had a power spike that transfer switch can weld the contacts together and you won’t get AC power to the coach. Just a couple of suggestions.
