With our expensive rigs I'm looking into power and surge protections.
I'm considering buying a Surge Guard 50 amp plug in type.
I have used a 30 Amp type in my 5th wheel and was very happy.
Surge Guard Model 34750 with LCD Screen
Rated 120/240V, 50A - 3850 Joules - 6/4 AWG Cord
Just introduced to the market in January 2012, the new 50 Amp Surge Guard portable with LCD display also offers more than twice the joules of power surge protection than the previous model. Continuously monitors for voltage and amp draw and reverse polarity (miswired pedestal, elevated ground voltage). Compact and easy to use, they plug in between the power pedestal and the line cord to provide protection. Designed for all travel trailers, 5th wheels and motorhomes with 50 Amp service.
Protects RV from faulty park power
Automatic reset on power restoration
Shuts off power when the following is present:
Low (<102V) and High (>132V) Voltage LCD display (English)
Multi-mode surge suppression
128 second reset delay protects A/C compressor
Continuously monitors for:
Voltage and amp draw (RMS)
Reverse polarity (miswired pedestal, elevated ground voltage) 3850 Joules of power surge protection
Convenient plug disconnect handles
Amazon $360 with free shipping and no tax
Camping World $380 plus tax and free locking hasp.
Been using this one for two seasons now, works great no idiot lights real codes. Just used it this weekend for a neighbor that showed up and was having electric problems with their coach, moved it to there power pole and showed him the post had no power on leg two, (post had a bad breaker), he went to the office they came out agreed and replace the breaker. This one displays the actual AMP load on each leg and saves history so when you return from sight seeing and things seem a miss you can check to see it the power cycled.
The newer versions w/LCD readouts and history to review are REALLY COOL. They do function as advertised and are a great way to SAVE all the electronics and electrical items you have. I had one very similar on one of my boats (long gone) and I now use the 30 Surge Guard. Perfect piece of mind while connecting to CG power. A note about the "locking" hasp, it only locks the power cable to the SG. You need to lock the power box cover (I carry an extra lock ofr that purpose). Seems some not-so-savory types have been swiping them at various CGs around the country.

I have voltage regulator but not a surge protector. I have it in the electric compartment in line between the coach and an extension cord going out to park power. Has save me on multiple occasions with bad power. I also use in line between generator to help with spikes and sags of voltage.
Have a Progressive Industries 50 amp hard wire. RVUPGRADES current price 285.00 Portable unit higher. May have saved me once already when the park I was in had voltage droped below 108 volts. Unit checks before shifting power to camper.
