I think the switch for the meter should be on the 9V power source.
I'm not sure why you have a switch in the ground to the battery and converter. The ground is typically never switched so that it isn't accidently lifted.
The hot wire for the converter is not fused.
You might clarify that shore power is circuited to the line side of the GFCI receptacle and the remaining devices are circuited to the load side. You kind of show that in the diagram but it wouldn't hurt to add a note.
I don't think you need the SPDT switch just upstream of the fuse box unless the SPDT switch for the battery and converter isn't a cutoff switch. It should be a DPDT with center off if you are using the switch to toggle between the converter and the battery.
The neutral and ground wire should be routed around the circuit breaker instead of through it since the breaker only works on the hot wire (but this is being a bit nit picky).
Hope this helps,

Bruce,
It helps a lot! Thanks for taking the time
1) I will bond (ground) AC and DC to trailer frame.
2)I had a switch on the 9 volt battery but didn't show it. I ran the meter line through a SPDT just because I had a spare one in my panel and didn't have an empty SPST.
3) I have the switch in the ground to the battery because I wasn't sure how the converter would function is the grounds were tied together. This shows my lack of knowledge... My question is this If the DC current is coming from the battery will the electrons return only to the battery, would they flow to both the battery and converter? How would this affect the battery?
4) I fused the hot wire from the battery as a catastrophic fuse. But now I have read that the catastrophic fuse should be on the negative pole between the batery and the frame. Please advise on this.
5) I did have the GFI wired as described but added info to schematic
6) The SPST upstream of the fuse box is a kill switch near the box. Not essential but convenient in my application
7) Please explain what a DPDT is compared to the function of SPDT. The SPDT between the converter and the battery positive line does toggle betwene the two sources of DC current, center possition is off. In off positiion it is also a cut off switch as the DC loads are not energized in center possition
8) AC neutral and ground are routed around the breaker but are in the breaker box
I appreciate your knowledge and your help
DEE
Grace happens...
