Hello,
I enjoyed reading your weights and balance review and your towing experiences bringing your new 5.0 back home. We are assembling our build list on a new 2018 5.0TA and I was wondering how you established the relationship between the kingpin on the trailer and the pickup box rail height of your truck. In visiting the show room model in Chilliwak last week I noticed the kingpin base hardware height was 46 1/2 inches from the show room floor and my box rail height of our new tow rig(Ram 1500 ecoDiesel) is 56". The hardware on the trailer can adjust to the next set of adjustment holes up but only 3". Did you have have the trailer kingpin assembly on the trailer augmented on your 5.0 to accommodate the box rail height? In looking at your wonderful setup in your attached picture, it looks like it sits down lower than your box rail and would hit if your trailer was 90 degrees to your truck. Can you share you thoughts on this for us.
