Proud new owner of a 22MLE. I have been reading up and it appears a good surge protector is warranted. They seem very expensive but so is the TT. Any recommendations on a good one, either plug in or hard-wired. Thank you.

I think what you're looking to get is an Electrical Management System, or EMS. An EMS is much more than a surge protector.
Chad and Tara (GD LIfestyle Ambassadors) from Changing Lanes have an excellent video on the topic.

We have camped many years with out any type of surge protector before our Grand Design unit and before joining such a Forum as this (these folks like to spend others money). With all of that said I do have a hard wired EMS from Progressive Dynamics. These are not too hard to install if you have easy access to do so. The plug in type on the post are another option but i have found 2 in campsites that folks have gone off and left behind. They are a little pricey and there are lots of members that have encountered situations where they actually saved there electronics inside there RV. The plug in one can get forgotten or "borrowed" by someone else. The hard wired takes a little to install. If you really want one decide on which style an go for it. I have not had an places that we have stayed that have caused us any issues with one and with out one. Just my 2 cents worth.

I use the portable version and it works fine for us. Both the hardwired and portable versions have their pros and cons. I like the fact that if I'm helping another owner with an electrical problem, I can plug my portable one into their pedestal and get a reading for them. And if you decide to change to a new RV, you'll have to remove it from the old RV, or buy a new one.

The technician said that they have never seen even serious melting of one of their units. Ever. This is in part because the guts of the unit are a very small circuit board, an actuator, and contact plates, none of which have the mass to create significant heat before being destroyed. They are also UL-certified - they are tested and proven NOT to catch fire.
Having started out years ago with the then-topmost 50-amp Surge Guard pedestal model for a few months I can compare the experience of owning both. No contest for me - internal mount is less trouble, less worry. I sleep just fine at night.Mark - 2018 Solitude 310GK - Ford F-350 SRW diesel short box - Pullrite Superglide hitch

They admit that it might be possible to get a "bang" out of one of their internal units if there was a direct lighting strike on the trailer, which would also make microwave, television, fridge, and most other things go "bang" too.

This has been an interesting back-and-forth evolution between external and internal (hardwired) EMS. Basic “surge protectors” are not really in this game. Over the years, we collectively convinced ourselves that it was safer if the unit was outside the trailer. Then we worked through Paul’s issue that could only be “seen” by a unit inside the trailer and the hardwired version gained preference. The latest evolution is the post unit that can see a missing neutral downstream which puts the preference back with the post unit (in my opinion).

Our Progressive EMS is hardwired and our's is under the fake fireplace. That was the first addition to our first RV and we had the new one in hand when we took delivery of this one, but it didn't get installed right away.Jerry and Kelly Powell, with Halo, Nash, Reid, Cleo, Rosie, and the two newest additions Shaggy and Bella..
