Converter charger
With all the information I've received from this forum. Any one know what the amps are that convertor charger puts out , and does it charge the house battery and run the coach at the same time ?

According to the 2018 Fuzion brochure, it's a 90 amp converter/charger. It's designed to be a "seamless device" that provides 12 volt power to the trailer systems and the remaining capacity is used to keep the batteries charged. Of the 90 amp maximum capacity, what is not being used by the trailer systems is available to the batteries. So the actual "battery charge amperage" will vary depending on how many lights and what other 12 volt loads (furnace, refrigerator, tank heaters, etc) you have turned on at the time. Reducing 12 volt load will increase battery charge capacity.
Keep in mind that if you bought the trailer from a previous owner, they may have "upgraded or replaced" any of the components in the trailer, so the OEM components may or may not be what's installed.....

If the converter is the original then you have either the 55 or 90 amp unit...
link to what Trekwood shows for you year/model

From this link you can get more specifics as well as the manual and TS guides..

When the trailer is parked and nothing is on, and plugged into 120, is the converter charging at 90 amps ?

The converter should be producing amperage sufficient to charge the battery. So, depending on the battery SOC (state of charge) will determine the amperage output of the converter.

I got it from the 2018 Fuzion brochure on the Keystone website: https://keystone-rv-dealer-app.cdn.p..._jan2018lr.pdf

This might be useful for you.. my WFCO converter is the 75 amp model..two GC2 golf cart batteries..
First image shows normal amperage draw plugged into the house .. nothing is on inside the fifth wheel (winterized)
The second image shows the output of the converter after I ran my hydraulic slides and hydraulic level up system on batteries only and then plugged back into the house 120 outlet..
That 9 Amps will taper down pretty quickly to about 4.5 amps or so and then charge at that rate till fully charged then converter switches to maintain mode at about 1/2 an amp.
