Hi Matt I have a holland with adjusting bolt out the front. Like you said turn it out tightens it. I have gone to shops that have kingpin and a long handle. They lock it in your fifth wheel. Then adjust it. But I do mine like you do. Great advice as always.
The fifth on the KW I drive does not unlatch at times, I never seen a mechanic, nor I adjust the fifth wheel. Could this help with unlatching from a trailer?
