New Campsite upgrade to 50amp

[Rsc373]

Okay I’m kinda handy but this has me a leery. DW and I are moving to a new campsite we were originally told it had 50amp service but then later we were told no it only has 30amp. Also they said we could out 50amp service in, and most folks do it themselves!����

So I went to the new site this morning and there is a 30amp and the normal 120v plugs in the box, (its not even a GFCI). I haven’t taken the cover off to see what’s going on inside of it. The question is how big of a deal is this gonna be to do on my own or should i just bite the bullet and pay an electrician to do it?

And now thinking about it, since the 120 isn’t GFCI should one just buy one of those 30amp and 15amp adapters and call it done?
