"... I currently am using between 50 an 60 ah per day. I would like to have enough capacity to go a couple days of bad weather"
So get two of those 235s for 235AH and 50% is down 117AH which is two days at your usage rate.
Your 280w solar is plenty for the 235 set. Some days the batts won't get down even 50AH because your solar will do some of the draw instead, which is like having an extra battery in the afternoon when there is solar to spare sometimes.
IMO go with that and try it for a while before getting more solar.
If you get into running the microwave off an inverter and so need four batteries, that is a different story from your 50-60AH as is. Now we are talking "upgrade!"
