I would not even consider plugging into a power source without a quality surge protector (even at home, where I have a dedicated TT-30R circuit). Many thousands of dollars of electronic equipment is at risk of damage or destruction in most coaches if the power going to it is bad. Spikes, sags, and bad grounds can damage any RV; those with 50A service must also contend with the risks due to a bad neutral leg as well. For the $200-400 a quality surge protector costs, it's a pittance to pay versus the cost of repairing destroyed electronics and/or wiring throughout a coach.

RV parks can have bad electricity. Its not always that the distribution is bad (but it can be), but also it can be overloaded (and there can be demand surges) that cause voltage to spike or drop. You want a surge suppressor and voltage regulator combo. You need to protect yourself against spikes/surges (voltage goes up) and drops (voltage goes down) as both can damage your electronics. Since you have a smaller trailer, I'm guessing it takes 30A service - Here's the one I have ($266): https://www.amazon.com/Progressive-Industries-EMS-PT30C-Portable-Protector/dp/B003AL23TC/
