Congratulations on your new cardinal! We have a 2013 3030 and we have had some issues, but I will have to say that FR is really stepping up and taking care of the issues. You should have 2 batteries minimum since you have the residential fridge. I would also suggest you get the 2 year warranty if you have not already. They really are beautiful RV's. Do you have the full body paint? If so, there have been issues with the paint cracking where it was painted over caulking. We had the same issue and they fixed it. Jerry.
