Propane stove and fridge

I bought a "Suburban" 2-burner stove and a small Dometic 3-way fridge.  I also bought a new regulator and a 20 pound propane tank.  There aren't any RV dealerships or service centres in my area, so I began calling around to local heating and air conditioning companies to see if I could get someone to hook up the gas lines for me.  I got a few "maybe" answers, but no one seemed willing to book me for a specific day and time.
I ended up buying my 3/8" copper tubing, flare fittings and a flaring tool, and I did the installation myself. (I am getting a licensed gas fitter to check my work.)
It went pretty smoothly once I figured out how much tubing had to extend beyond the flaring tool block to get the right size flare.  I didn't have much room to work at the back of the fridge -- just enough room for two wrenches and nothing else.

With just two appliances, the lines were quite simple: tank to regulator to a tee going to the fridge and stove.  The stove section went first, then the length from the regulator to the tee, then a short length to the fridge.
I got frustrated with the flexible pigtail connector between the tank and the regulator.  My RV supplier didn't send me a pigtail with my big parts order, and I was told that I could buy one at Crappy Tire.  And yes, I did find a connector hose made for RVs at Crappy Tire.

In fact, it was made by the same company as my regulator.  But the stupid thing had a non-standard threaded male fitting.  It was described as a 1/4" inverted male flare, but standard 1/4" flare fittings have a different thread.  This thread appeared to be a compression thread.  Crappy Tire had no other connector hose available.  In the end, I found a standard hose at a heating company.  The gas fitter there said he had never seen the kind of fitting on the Crappy Tire hose before.
Well, I got the gas connected, tested for leaks using a soapy water solution (yes, I found two and quickly tightened them up) and both appliances are running fine.  There's no gas smell, no bubbles, and the CO/gas detector hasn't made a sound.
