Sounds like you have low batteries on the house side and when you are running the freshwater pump it is drawing enough amperage to make the lights dim and breaker pop if the draw is too great.
When you are hooked up to shore power and shore water, with your freshwater pump turned off on the panel does the issue still exist?
OR -
Without being hooked up to shore water but being on shorepower with your battery charger on in the panel and freshwater pump on in the panel does it still happen? If it doesn’t that helps identify low batteries, since when on the charger it should for a short term keep the lights from dimming even for a little bit till the amperage draws down.
Just my thoughts to start to try to diagnose it, how old are your batteries, if newer you could have a bad cell causing issues and then lastly it could be a short or bad ground someplace which would pop breakers and also fuses if so equipped.
