instructions state 5 links between latch and bars
That is a good starting point for most people as most trailers that use WD have at least a 6 inch or larger frame and on a top mounted coupler(most common) will result in the bars either being level with the A frame on round bars or slightly slanted down in the case of trunnion style bars.
The 5 links is a minimum amount not maximum. The 5 links are needed for the chain to be able to move forward and backward during turns without the chains pulling the snap-up forward or backwards by crashing into the snap-ups.
A person should use the amount of links necessary under tension to get the bars where they should be. Once that is accomplished, the amount of WD provided can be adjusted by changing the tilt of the hitch head and leaving the number of links under tension alone. There is no problem at all with using the last link in the chain if that is what is needed.
I fully realize that doing it this way will result in a lot more work and time than just grabbing another link but the results in a properly adjusted hitch will be worth the extra effort.
