I agree with mainah, it might not yet be your power converter tripping th home GFI.
Do what mainah stated but also tell us some about your camper. Did you just get it and it never worked on your home GFI or you had the camper a long time, years and now it is acting up? Trying to find out if you inherited a problem this is s a new one.
Has anyone done anything with wiring in the camper, either on the 120 volt AC side or the 12 volt DC side? If they did, please tell us what they did.
If it comes to be the power converter, and you can post a pic of what the Centurion CS4500 looks like, then we can help point you to possibly a drop in new complete replacement power converter, or a just the converter portion and you keep the old fuses/circuit breakers. Centurion went out of business and American Enterprises took over and I'm not sure if they are still in business. Around the 2001 time frame the Centurion and the American Enterprises looked like the same power center, just a different label on it. This place has what can help you if you need to buy one. I have spoke to Randy and he knows his stuff and has good service and fair prices. He handles a lot of brands for a lot of different power converters Bestconverter.com https://www.bestconverter.com/
I have bought 5 of the converters off of him over the years to replace burnt out ones. But none of them tripped a GFI, they just stopped making 12 volts or other noises.
The fan not running in the power converter may be normal, pending the vintage, it would run when it calls for cooling due to increased load and shut off when not needed.
Hope this helps
