Hi Smk,
Yes, I use all three. The OEM cord runs the OEM outlets. I added two outlets and power the converter from the 20 amp. The 15 amp runs the water heater and an additional outlet for an electric heater. I used standard 120 volt male and female outlets, so I can switch between the OEM wiring and "boondocking" mode in about 30 seconds.
When I'm boondocking at Rural Churches and the like I run up to three shore power cords. At the moment I use #12 in various lengths. I was hoping to rationalize the "inventory" to one 100 foot #12 and the other lengths would be used on the heavier load items. None of the cords is "freeze proof" at the moment which makes running them out quite a chore.

Do you use these all together? I would try to cut inventory to three such as 30/70/120.
