2018-09-28-15-16-57.jpg This is a bathtub drain on a trailer in a very hard to reach location. It's leaking from where the arrow is. What's going wrong? Is it the piece above the arrow? Below the arrow? Has the glue washed away after years of use? Is this something I can fix with just a little putty that would make it last for a few years longer?

It is only a drain. I'm one who always fixes the right way, meaning cut it out and start over. Then again, how about that spray crap you see on TV that is suppose to stop leaks? I can almost guaranty you will have to replace it, but why not try. BTW, it looks like the leak starts below the arrow, but to be sure, fill the tub with water and check for yourself.
 
Those are threaded fittings. Take it apart and make sure the parts line up square to each other then retighten. It may also be a missing washer or the wrong size reducer.

Yes, that's what I did. I tried replacing the ABS parts attached to the drain with pvc, and this would have worked, except with the adapter I had to use, it was too long to attach to the p-trap. I ended up using a no-hub.
 
first off, this is an adjustable p-trap, with compression waste connectors. I would remove all of it and replace with 100% glued fittings.
 
Properly installed screw together traps do NOT leak. Possible one of the washer seals wasn't properly installed hence the leak. Get a new trap and just replace the old one with like components. Not expensive but awkward to get to.
 
For what it's worth, I agree with previous posters that you can replace everything with like parts. The challenge with pipes that thread together, and I use them all the time, is that the hot and cold water running through them can cause them to expand and contract just enough to loosen them. Don't overtighten, but make sure those fittings are really snug. And even though it's overkill, I would add a little bit of pipe dope around the rubber washer before threading the pipes together. If you have a compression fitting at at P-trap that requires no washer, I would recommend a little pipe dope around the male end before inserting it into the female end. Especially since this is such an awkward location to get to.
 
Is that mineral build up on the back side of the tub connection at the very top? You might need to put down some putty under the chrome flange from the top side and re fasten it. It looks to me like it's a metal tub. If it's fiberglass then put down some silicone calling instead of putty.

I like your inspection mirror with the built in LED's!
