Hi blklblventurer,
Congratulations on the new Pioneer and welcome to the Heartland Owners Forum.
I'd suggest you at an Electrical Management System. They're more expensive than surge protectors, but they guard against low voltage, high voltage, open neutral, reverse polarity and other common electrical problems, in addition to protecting against surges.
The two major vendors are TRC and Progressive Industries. Progressive's has a little additional function and also comes with a lifetime warranty.
Here's a link to the 30 amp Portable on Amazon. They also have a hard-wired version.
Some people have 1 TV. Others may have 2 or 3 or on some models 4. Some people have no TV. It's pretty common for trailers to ship with only 1 bracket, unless you order the additional TV with the trailer.
