What's your take on this? Thanks for your endulgence.
A 15/20 amp line that feeds your trailer by using a 30-to-15/20 conversion plug should allow you to keep you batteries charged, but probably not much else. It really depends on the converter that you have and how much AC it draws while making DC for the charger section.
A few summers ago while I was full-timing in a Monaco 40' Dynasty, I spent the entire summer hooked to a 20 amp line with 2 conversion plugs that went 50-30 amps and then 30-20 amps. I could run an air conditioner, and not much else, but it got me thru. And the price was right too.......FREE!!
Do you happen to have an 'amp clamp' ? It is a clamp type meter that will read the amp draw from a hot lead without breaking the wire. Sears sells them for about $50, and they read AC and DC amps. Very handy little device.
If you have/get one, you can clamp it over the hot lead going into your trailer and 'read' how much you are drawing. This would be a big help in diagnosing the situation.
