I carry a plastic bucket that I place over the head unit to keep the rain off. Never had an issue but just do not like having the head get wet.
Any power tongue jack I've owned I've covered with a simple tongue jack cover which is designed for the purpose, inexpensive, and can be left permanently in place and have never had any tongue jack issues related to moisture. A couple of years ago I bought this inexpensive genset cover and use it to cover the entire A frame anytime the trailer is parked between trips here at the house.
