Here is another update on my progress. My camper is finally loaded onto the truck and I have been making small adjustments to the right side link, measuring the height of both sides with a tape measurer (ground to top of rear wheel well) and occasionally monitoring the live data of the air bag system. After each adjustment of the link I drove the truck for several miles and rechecked the height measurements of each side before making another adjustment. I also cycled the system between the Alternate Trailer Height and Normal Ride Height several times.
My initial goal was to level the bed of the truck from the 1" difference that I had to 1/2" or less. By my measurements I am now within 1/4-3/8", with the right side still lower than the left. Honestly, the following photos of the live data are inconclusive as I did not check this data with the original link in place on the right side with the camper loaded on the truck. So I don't have a "before" and "after" comparison of these readings with a heavy load in the bed, just with no weight in the bed.
While I am overall happy with the results, I am surprised at some of my findings/readings as I slowly lengthened the right link. Just to reiterate, I leveled the bed by extending the right link slightly before loading the camper (see post #28).
1. I am surprised at how far I had to extend the link to raise the right side 5/8-3/4 of an inch. According to the link instructions from Revel Performance, two turns should result in about 1/4" change in height; so 8 turns should result in about a 1"change. I made the mistake of not keeping track of how many turns I made to the link to lengthen it, but I lengthened it no less than 12 turns, probably closer to 15 or 16.
2. As I lengthened the right link the left side height increased as well, but not as quickly. All told it rose 1/4", which wasn't helping me achieve my goal.
3. As I lengthened the link, I expected to see a difference in pressure between the two air bags, with the right side slowly gaining a higher psi reading than the left as I made adjustments. This did not happen as the photos show.
Here is the live data after my final adjustment. These reading are with me in the drivers seat (185#'s) and 1/2 tank of gas:
System pressure in Alternate Trailer Height:
It is easy to see the difference between the left and right sensor arms after my adjustments. Left on the left, right on the right:
While certainly a good improvement, and within the goal that I was hoping for, I am surprised that the right side isn't much higher than the left by now considering how much I lengthened the right link. I suppose that I should probably call this good and move on with my life, but I cannot help but wonder if I can do better. Perhaps replace the factory link on the left side with my other adjustable link and start shortening it? IDK.
Unless someone has any other thoughts or advise I think that at this point I will drive the truck/camper around for a few hundred miles or so while occasionally monitoring the height of both sides for any signs of change. I will continue to post updates if I make any further adjustments.
Thanks again to all that have contributed to this post! I wouldn't be where I am now without your help.
