Hey Greg, you could pretty easily add a 200 watt solar panel to your Keystone Montana with the Rich Solar kit part # RS37VR. What all are you wanting to run off the solar setup in your Montana?

I think I need to get lithium batteries first, I have 2 deep cycle batteries now and it just doesn't last that long. It's too confusing trying to figure out what size I need Any ideas?

@Greg Lithium batteries are going to last a long longer than deep cycle so that's a smart choice. You'd want to try and go with batteries that have a higher amp rating than what you have now to be sure you get a significant enough upgrade to make it worth it. Also you want to make sure you get two of the exact same batteries so that you are able to get the full potential from both since they will be wired together. What is the amp rating of your current batteries? Do you know about how much power your RV consumes? I attached a help article that covers how to determine how much solar power you'd need for you to check out as well.
