Big difference; MORryde axle on left and factory axles on right
The MORryde axel is a Torx (Torsion) Axel not a spring axle

Doc,
Whenever I hit a hump in the road (kind of like when crossing a bridge) I get some bouncing that is kind of like porpoising (a rocking motion where the front of the rig will dip and the rear will rise). It isn't sever, and it settles after what seems like a few of the rocking motions. Of course, bigger humps - bigger rocking. On our last trip we crossed a railroad and it was a pretty good bounce, so much so that a lot of cloths fell off cloths rod in the front closet (hangers and all).
Do you think the IS removes most of this rocking/porpoising/bounding motion?
Thanks for your thoughts.

Looks like those axle are going to make a dent in the trailer carrying capacity.

the extra weight is Unsprung weight so it does not effect your tow capacity.

the IS will remove all of the bumps in the road that you feel when the trailer goes over bumps or railroad tracks

Like I stated earlier we picked up our Road Warrior up on October 30, 2020 and are now sitting in Medina Lakes (NW of San Antonio). So the mileage we have pulled is a small sample size. From Elkhart, Ind to Medina Lakes we have put around 1400 miles on it, compared to 12,000 miles prior to the install. But the difference is extreme. It does take out allot of the bouncing over railroad tracks and rough roads, for us. The ride in the Ram is greatly improved as well.
As far as the addition in the weight, our tech Serigo told me it added around 400 lbs for the tri-axle a little under 300 for a dual axle rig. One modification Serigo had to do on our rig was cut the drain pipe for the rear gray water tank. It ran were the rear assembly needed to be installed. So when we get to Arizona I will need to reconfigure the drain line pathway.

The truck bounces more than the trailer does now!

Was about 300 Lbs added to the weight of the trailer but well worth it.
I had 8K axles put on instead of 7K.
Did fine for the 17,000+ miles I towed it out West, Canada & Alaska in 2019.

YES , however they don't have any of the issues with broken spring , broken spring hanger , broken wet bolts like what the OEM gives us when there new.
I had 8000 lb IS installed back in spring of 2018 , I had 7000lb axles from Redwood. My trailer gross weight rating is 16500lbs and these trailer with not one piece of gear or cloths weight 14300 lbs , true almost 3000lb of that was on the pin box. I had about 12,000 to 13,000 miles on the trailer at that time and the spring where flat and I pulled into Morryde with a broke wet bolt on the rear passenger side spring hanger. the spring was riding on the frame for possible 1/2 a day or 300 miles , It wasn't like that on my last walk around in western Ohio. Since then I have had zero issue and a lot smoother ride in the truck and trailer. We leave the coffee maker and the toaster on the kitchen counter and never see it move and inch after 500 miles of bumpy New England roads. The cabinets door all stay closed and it doesn't look like there was an earth quake in the trailer when we stop for the day.
100% sure I would have it installed in my next heavy 5th wheel if it isn't in it when I buy it ( I would not wait ).
Disk brakes , You Bet ~ Its a must at this weight if your going to travel anywhere and not worry about stopping in a panic. My stock drums where a joke compared to disk brakes.
