In the same position, got too much work now and falling behind.
I setup my 2 man system this afternoon. (should have taken a picture)
I have 1 pump and controller and 2 reels and they are split with a Y piece pile.
I have a hose-lock female pipe which can either go into 1 reel or a double male piece so I can quickly change to a 2 man setup and have both reels up and running in about 20 seconds.
Best of both worlds.
