I have a Demco 18K autoslide, I agree, works great!. However, I do have a slight problem with it. I take the hitch out every now and then to haul stuff then I'll put it back in, but it seems lately that when I go to put hitch back in, the left side pins do not go down into the hole far enough to latch. Have you had any problems like this? I have had the hitch about 2 years now, and this problem just started. Now, if I drop he left side in first it does latch, but the levers are hard to turn in.
