4 days to dry out is probably doable, but if it rains there tomorrow or later in the week it will be difficult for mild builds and next to impossible for those w/o lockers.
Some years back I went 3 days after rainfall - 37 MTRs locked F&R and had to winch once; buddy with similar Jeep but heavier had to winch 3 times. Lots of the time it was back up and gun it up the slopes.
