Does it have full hook up? 50 amp? WiFi? Cable?

Yes

Porta Jon on site, don't know why.

Yes, 50 and 30 amp., water shared between two sites, and no sewer. There are two dump stations. No wifi or cable, but pretty good cell service with Verizon.

Yes there are campsites for tents and also for RVs not sure about the 50 amp. But yes cable and wifi
