I don't think you would want to mess with the tilt of your EQ.....that adusts how much weight distributing you have. Try pulling the TV forward a little after you drop the coupler onto the ball. Sometimes if the ball sets too far back in the coupler, the pawl will not engage.
If your gas tanks are on and the fridge is in the automatic postion (the gas button not engaged), the fridge should switch from electric to gas without having to do anything. The gas button is there so that it would not switch to electric if you plug up to shore power.
