It's easy to replace, the two problems I see in your "future" are finding the correct replacement parts and gaining access to the back of the fixture so you can unscrew the old valve and attach the new one. On some trailers there's easy access, on some you've got to disassemble half the darn trailer to get to it.... I've no idea how or where yours is mounted, so no idea on how you'd gain access to the back side.
