Renogy DC-DC Test Results-UPDATE 4 (Better!)
Updates 23 June--new test with Renogy input exposed for voltage readings Update 25 June more readings Update 4 - 27 June-- fewer amps with fat wire were noted this time! ----- I have the 20 ampe...

The jumper cables are ok, but I agree the clamps can be tricky and need cleaning at times. Note drop along cables was 13.59 down to 13.21 with 30 amps.
I think my camper "frame ground" is not very good where the camper battery is neg connected and then/also to Renogy neg output. There is not much metal in the wood frame, al skin. The clearance and signal lights work right using the al skin.
The Renogy neg input/output is supposed to share the same neg side "ground" truck/camper but they only connect via 7-pin. IMO I need a better way to get the negs to the Renogy. Might be better with a camper that has an al frame. Something to work on anyway.
I did get a voltage reading outside using the pos end of the jumper while it was clamped with the 30 amps flowing and the neg from a camper jack, but the jack is bolted to the wood frame inside the al skin. I can't see where the main neg frame "ground" is behind the power centre, so no idea what it is using for metal.
In a MH you have the same frame for house and engine, but not with a camper or trailer.
I have no idea how a "table" could be used for the OP data. PT could construct one to add here from the data if that would help.
