2007 Suburban 1500 2WD towing issues

2007 Suburban 1500 2WD towing issues
I recently purchased a used Suburban 1500 2WD (2007), and was towing my 1999 Prowler RV. Once I get above about 40MPH, the Suburban starts to sway.
I've towed this same RV for years with a Dodge Ram 2500, and never had that issue.
Is there any suggestions to change something on the Suburban to make it more stable to tow my RV? New shocks? Other enhancements?

What is the trailer weight? Did some quick (not really...used to get good information from Edmunds.com...not easy anymore.) research.
Suburban towing capacity is 8100 pounds...Dodge is 9900. Towing past the spec'ed capacity is not generally a good idea...and can cause sway or handling issues.

It is never fully loaded. The Suburban should be able to tow this without issues.

Yeah...that is not too heavy...seems a 'Burb should be able to handle that easily.
Tires good? Maybe jack up the rear axle and wiggle all the suspension parts...make sure nothing is loose.
Just thinking...I had mistakenly purchased a 1-7/8" ball for my 2" trailer tounge. Maybe something weird in the hitch receiver?
Could maybe get someone else to drive it on the highway while you drive another car behind and beside to watch where the trouble starts. Maybe its the trailer suspension (doubtful if no problem with the Dodge) Maybe its the hitch/receiver

Might do an alignment check on your Burb.
Don't put over 630 lbs on the Hitch (adjust load in Trailer).
Make sure your Tires are LT type, and are aired up within 10% of Maximum Cold Inflation Pressure (trailer too).
Check height of Ball when loaded, should hold Trailer level (you may have to buy a different Hitch/offset).
Check bushings on Sway Bars.
Not all Burbs are Tow Rated the same, do some research. However I'm pretty sure your Burb isn't overloaded towing 6000 lbs.

As convenient of a storage place as it looks, the rear bumper area of a trailer is the worst place to put weight...ideally over, or just to the front of the trailers axle is the best...

Another thing is the hitch receiver on the GMT900s is several inches higher than on the GMT800s. Requires a drop down hitch of about 9" for most trailers.

Kryten,
If the Tongue Weight and choice of a proper offset on the Hitch is going to be difficult for you, set your rig up like you were going somewhere, and take it by a good Hitch Shop. They'll be able to do a tongue weight, and select a Hitch that will set your Trailer right. I may be speaking out of school here, but here in Houston I go to Master Hitch. Great guys and I really recommend them.

The Suburban can handle the trailer just fine. If you're getting sway, then it's because the tongue weight is too low. Shift cargo towards the front of the RV to add weight on the tongue.
The Ram likely has a longer wheelbase than the Suburban (extended or crew cab?), which provides more stability when towing a travel trailer.
The trailer should be level when hitched and loaded. If not, you'll have to replace the hitch with a higher/lower drop.
Going to the scales is always a good idea, to make sure everything is squared away. CAT scales charge $10 for a weigh.
