Don't know what your Crown batteries capacity is, so what I did may be more than you need. When installing my solar setup, I committed early to four Trojan T-105's and did the math on their size. Wasn't interested in spending days on end dry camping, just overnight and occasionally two. I settled on 100w for each, a total of 400 watts from four different panels. We can run the batteries down to 70% by our Triminic and they'll charge back up completely over one sunny day of driving.
