It is a huge gamble to operate without a surge protector. We plugged into a new 30 amp RV plug installed by an electrical contractor in a new RV garage. The “electrician” had wired it to 220 breaker, even though it was in the metal RV storage box with a big sticker on it not to wire to 220. It fried everything in our trailer that was on when we plugged in-tv (it is partially on even before you turn it on), refrigerator (burned out the electrical board as it automatically switched from propane to electric when plugged in, it ran on propane for the rest of our trip), etc.
Several thousand dollars and weeks later every thing had to be checked and repaired/replaced. Luckily the builder paid the bill. We purchased a surge protector immediately. We have found that campground electric systems are sometimes sketchy-no ground wired, reverse polarity, power surges, etc. We were lucky it wasn’t our Vegas because there are a lot more TVs and other things that could have cost thousands more to fix.
