How much solar power do you have, wish you had?

I have 2 group 27s in the camper. We can usually go 2.5 days before running the Honda. My cargo trailer has 2 6v Duracell with 150 watts of solar. I just installed them and they are keeping the batteries at full capacity. More usage will tell the story for me. I'm planning to add 2 100 watt panels to the camper soon. I am interested to see others responses.
