Haha, indeed you are correct. Most high amp draw stuff comes from my house batteries and bulk modified sine inverter. I have an 800 Watt pure sine generator
that is the primary thing I connect to that Noco port. It literally cannot overload the connection.
If I run something that takes more power than that I use the batteries. Such as a quick burst with my microwave
or one of my small ovens. My constant use power comes from a modified pure sine UPS. This provides 600 watts constantly on demand to run my computers or other electronics. The batteries are mainly charged with a set of Renogy solar
panels on top of the trailer. basically, the amount of power I need to send into my trailer is quite small. the biggest load at any one time is 1300 to 1500 watts from a heater or my largest oven on its highest setting. I only use one such thing at a time. I came to the conclusion that I have no need for a 30 amp system in my Scamp
after thinking about the fact that I have run it for 3 years off of a standard utility extension cord and a 15 to 30 amp adapter. That includes running my AC all summer, AND cooking at the same time.
YMMV and all that.
Besides all of that, it's easy to put a 30 amp connector in the same hole at a later date.
