Looking for guidance and designs for marine application.

Hi folks.  I tried searching but I think I don’t know the terminology well enough to be effective. I am hoping some kind souls will help me out with some guidance. 

I am looking for a budget system, about 400AH I think should be sufficient based on very rudimentary load calculations, that will work reliably and integrate with the house system on my 33ft boat. I have tried using ChatGPT and the results, not surprisingly, are less than confidence inspiring. In fact they are down right laughable.  Between the inconsistency and outright errors and omissions it is utterly useless lol. I have searched for premade packages but nothing seems quite right or is prohibitively expensive from retailers. I reached out to one company who shall remain nameless and was quoted over $5000 for material only 🤦‍♂️.  I am sure it can be done better for less.  

I have been able to glean that I probably want lithium batteries and commensurate solar panels.  Beyond that I am a bit flummoxed.  

I have a gas generator on board but I hate how loud it is and would like to relegate it to emergency and time of high energy usage only. 

Is there a forum section that lists specific packages, I guess they might be called? That may provide what I am looking for?
My budget is as much under $2000 as possible.  And I have a retired electrician buddy who will help with the install but neither of us are experienced in marine or portable(?) solar. The learning curve is quite steep and I’d like to have the system in place and tested prior to splash in couple of months. 

The other thing is I would love to be able to pull the system in the winter months and use it on my travel trailer when we head south after the summer. 
I welcome any suggestions on resources that can be provided. 

Thanks!
