Suggestions for RV panel install, long run
Greetings, everyone! I tried a forum search but could not find what I wanted. I recently purchased my 1st trailer and joined this group. I'd like to set up RV hookup on my sister's property in the ...

The photos are a bit on the small side to see exactly what's going on. A wiring diagram would also help. This is kinda what I'm thinking:
In the main fused disconnect, there are smaller wires running off the load side of the lugs. Not legal and not sure what they're for. If the main switch feeds two loads, there should be some kind of panel after it with a breaker for each downstream load. What size are the main fuses and what are the wire sizes connected to the load side lugs?
It looks like there is a reduced neutral in the main disconnect switch. This works and is permitted in houses where there is generally a somewhat balanced total load and the neutral sees less current than the hot wires. Not sure if that affects anything or if you need to try and better balance loads, but just putting it out there anyway.
Main service grounding should happen only in the main disconnect with ground rods (or code alternative). There would normally only be one size (not sure what the code size would be) main ground wire but sometimes there can be a small gauge ground wire for the telephone or CATV service. In the remote RV panel, grounding should definitely happen there if there is no ground wire in the overhead run back to the main disconnect. The neutral and ground should NOT be interconnected in the RV panel, but the enclosure must be grounded and connected to the ground bus inside the enclosure and to the ground connections on the receptacles. There should be a ground bus somewhere inside the RV panel. I *think* the NEC now allows grounding at remote RV panels/pedestals but does not require it - if there is a ground all the way back to the main service.
The meter base looks correctly wired as long as the neutral is isolated from the ground connection there. The ground bus needs to be connected to the enclosure which it looks like it is.
The RV panel is just like any "ordinary" house panel except that it has receptacles in it. There needs to one or more ground rods as per code which also depends on soil conditions.
The work looks great. Just add a faucet and sewer connection and you've got your own personal one-site RV park... :)
