Wiring 15 amp shore power to MultiPlus using NOCO GCP1

I have a MultiPlus 2kVA 120V currently connected to a 30 amp shore power inlet that I haven't yet installed on the van. I have a NOCO GCP1 AC port that I'm considering instead of the 30A inlet, as I don't expect to camp at RV parks very often and don't need 30 amps for my loads. The NOCO uses 14 AWG wire and has a female plug, and I'm not sure what is best practice for connecting this to the MultiPlus AC IN, which is currently wired to the 30A inlet via 10/3 wire. I assume I can't just wire a plug onto the 10/3 coming out of the AC IN and plug that into the NOCO. What's the right way to do this?

You could fit a NEMA 5-15 male plug and cable to the inlet of the Multi and plug that into the female of the NOCO.

You could also cut off the female NEMA 5-15 off the end of the NOCO's cable and wire that directly into the Multi.

Or as you suggest, fit a NEMA 5-15 male to the end of the 10/3 going into the Multi.

All these would be legal since the NOCO's inlet is a 15 amp rated plug and that's all you'd get coming in from the source.

You could also install the 30 amp inlet (which is most likely a NEMA L5-30P) to the side of your RV and use a NEMA 5-15P to the L5-30R adapter to feed the inlet.

Most people use a TT30 to L5-30R cable from the pedestal to the side of their RV and use a "dog bone" to convert to NEMA 5-15 when needed.
