Converter replacement
I need to replace the WFCO converter that came with my trailer. Past experience with this brand has shown me poor longevity and charging cycles that can fry a good battery. I seldom dry camp but w...

My calculation shows about 16 amps AC available from the generator. I can't decide if I can safely go with the 55 or 60 watt converter and not overload the EU2000??.
I think you mean 55 or 60 amp converter. And that's at 13+ volts, so it's not equivalent to 16amps at 120v. 60a x 13v = 780 watts so your 2000+ watt generator will be fine.
A few lights is virtually no load at all.
Your "assuming" the power supply is 100% "efficient" and has perfect "1" in the pf department.
No power supply is 100% efficient, typically efficiency will range upper 70% to mid 90%, and the rest is heat..
Read HERE for more information on switching power supply efficiency..
Read HERE for information on Power Factor.
Switching power supplies are not 100% efficient and most have a pretty low PF.. Both details means on some converters which do not have "active PF correction" can consume a lot more than 780W for 60A at 13V output..
A PD9160 or PD9260 (both are 60A converters) can consume as much as 1000W at 120V under full load due to having a low PF along with the typical efficiency loss.
