I see you also have a Dodge. it sounds like you switched from Energy Suspension to StableLoads?
did the ES ones finally fail on you? Why did you switch? Would you recommend someone with ES (me) that it was worth switching?
mine get pretty distorted when I am loaded, but my truck fully loaded is like 6300 lbs max (tires limit) and I am running just under 6000 lbs.
your truck will allow you to go way over my numbers.

The ES's and SL's were on my 2005 Ford F250 (I even tried a hybrid mix of both). Without going into a long history of my testing various setups, The ES's never failed, but they compressed too much when under load turning a 3" pad into 2". The F250 sits almost level when unloaded compared to the F350 that sits 2" higher in the rear due to a taller axle block. Although I preferred the unloaded ride of the ES's, I had to use my Firestone airbags to take up 1" of sag which then caused more bounce since the overload was not fully engaged. By using the upper and lower SL's, I was able to haul my 4000 lb Arctic Fox with assistance from the bags. Once I added 1000 lbs of weight distributed tongue weight from cargo trailer, I used the bags to get back to unhitched height. With 19.5" wheels, I was typically running 7000-8000 lbs on the rear axle.
My 2015 Ram 5500 is running the stock suspension without any aids and I don't even feel the 8000 lb trailer behind me. Our plan is to go to a 6000 lb mega TC in the future and was this was the reason for replacing the Ford. I pulled the SL's off my Ford before I sold it, so they are avaible to mount on my Ram if I need them in the future. The upper ones will work fine, but the lower ones will not fit the gap so I really should find them a new home.
