Ironically, I had a hardwired system and I am switching to a detachable type. I occasionally forget to close the mouse hole door. Testing out the trailer in my yard, I left the door open and a mouse family accessed the cord cubby hole. We thought we had the mice removed, yet when we camped and I actually remembered to close the door, a trapped mouse tried to gnaw through the door and cable. When we left our campsite, we opened the door to feed the cable in and there was the mouse, starving and dehydrated. It ran back inside and, then sometime later in the trip, it died. Made a great vacation, let me tell you.
I've ordered a Furrion conversion kit for RVs and Boats. It locks the cord into the receptacle so it can't be accidentally detached, making it effectively hard wired. However, it also gives a completely enclosed power access that prevents ingress from outside critters.
Pics this weekend, once I get it installed. No luck on getting any information from Suburban on my manually lit stove top, but I'll keep plugging away.
