When Your 5'ver is at Home - Do you.........???

I keep my 50amp 5er plugged into a dedicated 30amp circuit full time when its parked at the house. I used a 50a Marinco camper side to 30a plug on the outlet side, cord set.
this was installed when we first had the pop up and could park under the carport and raise it up to load and unload it and I could run AC when it was popped up.
Still use it because of the trouble to run a 50a circuit to the same spot and then I would have to use my nice 50amp cord set with it sitting out of all to see.
