Drip in bathroom sink.

Terrible pic, sorry, not much room for a old guy to move around! You can see the drop just to the right of the tee. We are lucky that the cleaners stored under the sink were in a large plastic container and noticed the water at the bottom. Another good reason, every once in a while to : (A) check under the kitchen & bath sinks.  (B) Shut down the shore water and go to the pump and listen for it to cycle, especially if you've been on some nasty roads! We dodged a bullet on this one, though fixing the leak is not in my job description. Thankfully, we have a tech that lives n the Park, who has tools and fittings. +, he is about 30 lbs lighter and much younger than I ! ^.^d

The ones that concern me alot are those that are hidden, such as the shower valve in the wall behind the stove.  I had a leak there once and alot of things got wet before I found it and fixed it.  there are also a lot of fittings under the couch associated with the fresh water pump and I have had leaks there also.  To help out there, I installed an alarm system in those areas that will let me know if a leak occurs there.  And for sure, always leak check the system when you can by turning off the shore water and listen for the pump to cycle. 
(watch the toilet flush valve also)  Have a great day  ----  Fritz

Get plastic containers large enough to fit side to side, same with the kitchen.  ^.^d

Care to expound on your 'alarm system' ? ???

Leak/no leak is EASY to verify:  Turn off shore water.  Run off the pump/tank.

If the pump cycles when there is no demand, one of three causes:
LEAK
bad check valve in pump
bad fill valve/fill valve not fully closed

So, if the pump cycles with no demand determine the cause!

I would try and recrimp it Mike,the trouble with those old lines is it's a bitch to get that old grey stuff to take a new fitting,it's brittle
and those old fittings have o-rings in them and they are not 100% like a pex fitting.

It may be the adaptor above that's leaking and not the copper crimp ring.

That was my thought too and all it would need is a bit of tightening, or, a new seal inside. So simple fix.

Mike, they make some barb fittings that have a nut that tightens over the barb.  I don't remember the name but you can pick them up at mobil home supply stores.  I always had good luck using them on the grey tubing.  when you cut the fitting out you will probably have to splice some pex in line  unless you have plenty of slack line.  Unless your tech friend has the small offset crimp tool
it will be hard to get into the area to crimp.  Also, (just my experience with grey tubing)  I have tried to re crimp and it always made the leak worse.  Hence the barbed fittings!
Just my 2c worth
Glad you caught it

 Here is the one that we use. I have 3 of them, one with the remote sensor under the toilet bath sink area. Another one in the water pump/ wet bay area and the 3rd in the kit sink area.
They are VERY sensitive. Two wet fingers will set them off and the batteries seem to last years.

 Annoyingly loud also.  Like your smoke detector

Done: amazing how brittle the old pipe had become. I put 'stand-offs' in between the hoses, but it's just the age and the dryness.

All that the alarm module has on it is HONEYWELL  It is a flat wire sensor that lays flat in the area to be monitored and is  wired to an alarm module that you can install in an easy to get to area.  As I recall, it was advertised as an alarm sys to monitor leaks in hot water tanks.  It is installed under or around the hot water tank to signal any leakage.  Sorry, can't be more help than this, Google may have more answers for you.  ----  Fritz

Oddly enough, we found all the repair parts locally. My buddy had the crimping tool!

 I try to de- pressurize the water system when I leave by turning on the sink until the flow stops.  This way any leak flow may not happen while you are away. And the system can rest easier.  Pump off, water heater off.
