Access to the back side of the power panel was pretty easy on the 5th. The back wall of the basement comes out and it's wide open. I located the remote display like Camping did. I had a pole-mount for the HTT and was always concerned that it would go for a walk-about or I would forget it. Neither happened in the 2-ish years I used it tho. But a built-in is much more convenient and I know it won't get lost.
I've developed the habit of turning the main breakers off in the panel when packing up. I like watching the display telling me everything is OK before I snap the breaker on when setting up.
