What to keep in mind when putting in meter for rv power?

I’m hoping to put a new meter on a lot we own to be able to camp. What should I keep in mind?

This would be new service and I assume I’d want to do enough for “now” but what else would be nice to have down the road?

Starting with I need 30 amp power but I’d also put a 50 amp plug for friends. I’d also put two 20amp plugs.

But what about a light on the post? For security or safety? Or maybe a wifi access point/starlink?

Was thinking of running a extension chord inside to a dehumidifier that could run when we are away. Drain into the gray tank and out? Will need to research that but would love to keep the inside dry!

What other applications would make sense?

Thanks!
