To me it'd be a no-brainer to have a hard wired unit if we were full timers but we're not.

Wondering if it'd make more sense to get an exterior unit considering:

- We're weekenders
- I can see where we might change out rigs sometime within the next 5yrs

Also, I can see benefit in being able to test different pedestals w/out having to move the rig should a fault be found at an initially assigned spot.

Understand a big downside is potential theft of exterior EMS units, just wondering if other than that there's much of a downside to having one.

One advantage of a hardwired unit is you can't forget it. Also, many hardwired units offer more protection than their portable counterparts: https://www.progressiveindustries.net/portable-hardwired-comparisons

I secure mine with a heavy chain and a good lock. They would have to come prepared and/or destroy the pedestal to walk off with it.
You can use it to test before pulling into a site or you can test with a less expensive tool. Mine partially failed under warranty and
was repaired and returned in under a week. Hard wired maybe convenient but its not for me.

Rocky's lock suggestion is a good one.

Depending on where your 30A/50A shore power cord is stored, you can plug a portable EMS like the PT-30X into your shore cable, keep the portable inside the (lockable?) electrical bay compartment, and buy a second 30A shore power extension cord, and use that between the electrical bay/EMS and the c/g power post. Cheaper to lose an extension cord than the EMS. It's how I do it.
If your portable ever fails for any reason, and you're under warranty, it's easier to send it back, than unistalling the hard wired versions or trying to replace parts in it.
Not sure about "more" protection from hard wired units. Dubious?

My 2004 hardwired unit is in the second rig. In each case it's installed without cutting/splicing any existing wiring so trivia to remove and restore original wiring. It also has a remote display inside the rig which is a HUGE advantage over a portable. Voltage, amps, error codes are all easy to see. A data wire has to be routed to the remote.

we chose the hard wired unit for convenience (we are nit FT). a bonus was the remote monitor mounted inside the coach.

Ya gotta plug it in, don't you? You can easily see the portable unit's display as well, when you're outside the coach doing that. If it reacts to something and cuts power, you're not likely going to be able to either trouble shoot or resolve it from the comfort of the inside of your coach, you're most likely going to have to exit the vehicle at some point to resolve the problem, so it's really not a huge advantage. Very few shore power issues occur inside your coach.
