Suburban 2500, 2500RL and Equalizer woes?

[Flip94ta]

Hello, I’m not sure if I should post this under tow vehicles or in the general section.

I am the happy new owner of a 2500RL. I bought it four hours away in my hometown, we camped there a couple nights and then drove it back to Detroit. It’s our first camper and the unit itself has no issues so far.

It drove fine on smooth roads but I did have an issue when crossing bridges or any hard dip in the road. The vehicle will rock front to rear over the dip and then the trailer will send an even bigger rock front to rear through the vehicle. It is only one cycle each so I feel the shocks are trying to do their job The suburban has a pretty stiff suspension and I just installed bilstein 5100’s on it. The empty ride is okay, maybe jittery on our crap roads. I set the tires to 47-62psi from factory 50-60 setting. I knew going in that it’s basically a 3/4 truck on a shorter wheelbase and the ride would be rough but how do I know if my hitch is set up right? I don’t think the mechanic test drove it. The front end felt planted and I didn’t feel any sway. I did see the end of the trailer wiggle 3-4” maybe once per mile, I associated that with the stiff head wind. It almost seems like I need even stiffer rear shocks.

The Burb sits nice and level, the mechanic pointed out to me the trailer nose is just a touch high and I could lower the equalizer to the next, lowest hole. I think I counted 8 washers on the hitch, does that seem right? I would estimate 850lbs on the tongue. It’s a 10k hitch.

Some specs on the Suburban, it’s a govt spec 2500 model, possible front plow springs, torsens cranked all the way down for lowest height, front ride height 39.5, rear 39 3/4. I have not measured hitched up yet. Tires are Firestone Transforce AT’s, 265/70r17. Soon to be Michelin’s. Payload is 2109lbs.
