I cut my cord with enough on the trailer end to hardwire to the EMS, then cut another piece to go from the EMS to a hardwired inlet, so I can have a detachable cord. I personally don;t see much to be gained by any of this if you still have to fish out a plug and connect to it, but that's just me.
My EMS is also installed with interlocking 30A plugs, so in the event it should fail, I can remove it, reconnect the plugs and I have power again.
I'm also going to add a second 30A service and run it to a second panel so I can split the loads between the to services. That will run off of a 50A breakout box that I already have built. I also have an addition 20A inlet installed that I use to run space heaters or anything else that I don't want to run off the 30A service, so when completed, I'll have 80A of service.
