What kind of electric hookups do most campground offer? Standard 110 outlets, plus the big 30 amp outlets and 220?

Most have 110v, 30a/110v & 50a/220v, depending on size of your RV needs.

If your RV needs 50a, and the RV park only has 30a, you’ll need an adapter for the different plug sizes/shapes, and may have to limit how many users you have on at the same time in your RV.

Most will have a 50 amp, 30 amp, and 20 amp.

-The 20 will be a standard house outlet.

-The 30 will be a 3 prong RV outlet. It is 120v

-The 50 is a standard 4 prong outlet. It is not a 240v outlet. It’s more like a 2 phase 110.
It is wired the same way as a 240v. The 2 hots work independently.
I have my 30amp camper plugged in to 50 amp outlet with a splitter.

Do not put 240v into any camper. It will fry the component and may burn it down

Most campsites have a 30-amp plug.  You'll probably want to also purchase a 50-amp pigtail.   I've sometimes reserved a "top of the line" spot usually meant for big-ass coaches, and the only outlet was a 50.

It's only $15.

Most have 30A 110v, some have 50A 110v... the 50A are not 220v, they are two separate 110v 25A circuits.

Along with discussions on power... I installed one of these in ours so we didn't have to worry about using an external one.

In our recent rv'ing experience, all online bookings will list which outlet types each individual spot is equipped with. Also water and sewer.

A 30A will keep up with one AC and the rest of the rv functions. A 2nd AC will require the 50A.

The spots with 50a plugs are more likely to be pull-throughs, and longer.

Our 28' bumper pull was upfitted from a 30 to a 50 with the addition of a 2nd ac unit. Key in full sun.

As has been pointed out most campgrounds will have a mix of 30A and 50A hookups, usually you'll find more 30A sites than 50A sites at a location. It's a good idea to carry adapters to cover 50A/30A and even household 15/20Amp plugs. My stupid big Momentum 395TH has 3 AC units and requires a 50A service to run all 3 at the same time. I can get by on a 30A service but I have to do some power management, the trailer has a monitor that will automatically shed loads if I overdraw the available power.

A surge protector is not a bad thing to have and I carry an extension for my main power cord because sometimes the power pedestal is not always located close enough to where you want to park the trailer.

You should buy the following:

Quality surge protector.  Our trailer has 30 amp service. So I bought a Power Watchdog PWD30
50amp to 30 amp adapter cable
30amp to 115VAC adapter cable
10ga 50ft extension cord

This should cover all power scenarios.
