Wow, sorry to see that Lochsa. The question is how handy are you? I've seen spider cracks in the gel coat of a friend's MH which he repaired with a gel-patch and eternabond but these are quite a bit more extensive.
Personally, I would get it in to my dealer to find out why this is happening. If the RV is not in a covered area and you cannot take it in for some time, then place a patch, tape or sealant to avoid further water intrusion.
