Trailer Bounce oscillations
Hi all, I have some experience towing small toy trailers < 3k lbs, but never anything as big or heavy as our new toyhauler. Is it normal to feel the back end bouncing / oscillating up and down w...

Sound like you need more damping (aka better shocks) on the rear of the truck.
When you did the lift, I assume longer shocks were installed? The base shock on most lift kits is tuned for a softer ride, and the base shock usually is just an OEM-grade twin-tube shock. You'll see a huge improvement with a mono-tube shock, especially one spec'd for your heavier load.
Yes, they are Fox 2.0 Performance Monotube shocks.
Not clear what their load rating is. I'll see if I can find out.
The back is raised with a 2" block between the axle and the leaf springs though. Leaf springs were left alone for the lift (other than the lift block).
How they are valved is not readily available that I've found (IE compression and rebound force, damping speed, etc) however they are marketed as an "off road" shock, which can also vary greatly, IE a crawler shock is valved differently than a high speed Baja type shock.
Fox does list a different P/N between 2500 and 3500 for most applications where the shock length is presumably the same, so maybe it's a stiffer/slower action shock for a 1 ton vs a 3/4 ton.
But any shock that is valved for any off road application will likley have a soft initial compression damping and relatively quick comp and rebound characteristics. Which is opposite of the ideal shock for heavy loads/towing, where you want heavy and slow.
Like another poster here who can't seem to get "all" the "sway" out of his trailer setup, I'm not sure I'd go down any more rabbit holes with your setup.
You said it pulls good. This is one of those diminishing returns things. Less time "perfecting" the ride = more time camping and riding!
