A 1/4 full fresh water tank would take a longggg time to freeze at 30 degrees... Even the lines running through the RV will take time to freeze.
As I stated - no guarantees - but personally I wouldn't be concerned until temps drop into 20's and stay there for longer periods.

Along with that: remember that the coldest overnight temp is usually right before sunrise. Thus if the low is going to be 30 or 31 your rig will likely only see below freezing temps for an hour or two at most (maybe only a minute before sunrise..).
