Decided to go with the joyrider. I have only towed about 10 miles but it seemed smoother on the concrete interstate, taking off for Dallas tomorrow, will most definitely be able to tell if we made a difference and will post.
Only issues during install were that the u bolts weren't quite long enough to go thru the 3/8" plate AND the straps, the manufacturer said the straps weren't necessary with the 3/8 plates. They are MUCH thicker than what Jayco had on. Jayco also didn't use washers on the u bolt plates, so I still don't have washers. If I start to see any wear on the plate holes I may add those.
Its between 4 and 5" from the ground to the bottom mount. The bottom mount is pretty beefy, if it did hit I am sure it would just lift the trailer. If the height is a problem down the road, flipping the Axle would definitely give it more height (both on the shock AND the trailer), I would like to avoid that.
Total install time even after breaking drill bits and going to the store was about 6 hours. I did it in the storage lot with no AC power other than charging the drills battery from the truck when I could. Cordless impact is worth its weight in gold for this install.
