“Weatherproof” padlocks for boat/trailers

Anybody have a recommendation for boat and trailer padlocks? I would likely need a set of four and want them to be keyed same. 2 for trailer doors, one for enclosed trailer tongue, and one for boat trailer tongue.
I would buy a 5th if sizing worked out to use to secure mu ulterra on the mounting plate, as well. The master locks I’ve used the last few years had the plastic cover for the keyhole, but in upper Midwest winter weather always require me to put a lighter on the keyhole for about 30 seconds in order to be able to turn the key.

They all freeze. Their tolerances are too loose, lube and heat are your friends.

One day I’m gonna buy me one of those cordless heat guns. Safer than a torch, but more oomph than a hair dryer (and cordless as well)

Combination locks?

I use the standard keyed master locks and just spray them. Had the same locks on the boat (tongue and for spare) for 5 years with no issues. My boat is outside about 90% of the year.
