I just bought my first trailer . WooHoo ! ! I need to buy everything, including a surge guard for RV park hook-up. Why are some 30 amp protectors costing under a hundred dollars, and others are over three hundred dollars ???

Thanx ! ~David

Congratulations on your purchase.

If are totally new to RVing, in general getting anything Camping world has to offer will probably do. And get used to paying premium prices for everything RV.

Camco is a reasonable brand with a proven track record.
Surge protectors and water pressure regulators will protect you from really bad connections or variable supply sources caused by many factors including other users hooked up to the same connections.

So surge protectors and water pressure regulators are like insurance, they protect you from unknowns and are worth the money.
Look at it this way, would you rather have a flooded trailer from blown pipes or burned out electronics or a possible fire?. Spend the money on these 2 items

The Camco model 55301 is top of the line so better insurance.
Note, after plugging it into the panel it will take 2-3 minutes to check the power supply before actually opening the connection to the trailer. Be patient.

As for pressure regulators get the Camco 40058. It shows the pressure going into the trailer and is adjustable.
Note: You would need a seperate gage to read the pressure at the faucet like this from home Depot

Why would you want to know faucet pressure? To help diagnose water flow problems, is it the supply, the regulator, the filter, the pump etc. You could even connect it the regulator to verify the regulator gage is reading correctly.

These devices are both the first things to connect to the Services before anything else.

Another must have, and at some point without them you’ll wish you had them, are wheel chocks.
There are any number of situations where the trailer can roll, and if it can happen it will.
Don’t spend a lot money on fancy scissor devices that you’ll only wreck if you drive off with them installed and possibly wreck tires too.
Go old school with 2 sets of rubber chocks from Harbor freight, dirt cheap.
