During our FT travels of 7 yrs we have been in 100's and 100's of CGs from State/National, COE, public, private, fairgrounds etc.
The one constant..........hookups could be just about everywhere.
Majority left side----middle to rear
We carried three 25' lengths of water hoses, 4 sections of sewer hose that expanded from 3' to 15' and have on occasions used every bit of them.
Only carried the 25' OEM power cord........but we have dual power connections. One front and one rear so we have been able to reach all power pedestals without an extension cord.
