The first (and probably easiest) thing to check would be your tongue weight. It should be 12% to 15% of the total weight of your trailer when loaded.

I agree that tongue weight is very important, I think with sway you have too little tongue weight. I would also suggest LT tires if you are using P , passenger tires, this will help alot as well.

What weight bars are you using with the E2 hitch?

Brian

Thanks Mike,
The 2600 RB dry weight is 5795 Lbs. and tongue weight is 594 Lbs. or 10.25%. We have ~ 20 gallons of water in the fresh water tanks (166 Lbs.) or slightly more than 13%.
But since the tank is not at the front of the tongue, I may need to add another 10 gallons or so. Possibly 20 gallons.
Then readjust my sway bars or hitch pivot washers.
Bill

Brian,
We have the round bars with the e2. Because of our farm experience, I have used LT tires for 40 years. When I had a 3/4 or 1 ton, I used 8 ply with 10 ply rating. the current tires are 6 ply. LT.
Any comments a on shocks?

Bill

With over 100k on the shocks, I would definitely consider changing them.

I run a Bilsten on my TV.

What is your unloaded hitch height, loaded hitch height, unloaded front fender height and loaded front fender height? These 4 measurements are usually critical in setting up the WDH. You may need to add sway control if it's not built into the hitch.

X2 on Bilsteins and LT tires. Your loaded tongue weight might be low... worth a scaled measurement. I have no experience with the E2.

Mike

Is that your actual measured tongue weight loaded or the brochure tongue weight. I only ask because that's a pretty specific number, I know my scale isn't that detailed. If it's the brochure weight, you'll want to get your actual tongue and trailer weight and start with that. I agree the shocks should probably be changed but I don't think that's your issue.

We had a 2600RB that I towed with a 1/2 ton Silverado for a couple of years.
As far as shocks go, I think you likely need new ones but thats not going to help with sway.
Others have already mentioned that an actual tongue weight and overall weight on your trailer would be in order. The 2600 has enough storage available that its easy to create a weight imbalance.
The P tires on mine were the limiting factor and you have already solved that
I dont have any experience with your particular hitch. I ran a Reese "dual cam" hitch. Once I got the trailer loaded and the hitch adjustments dialed in I thought it towed pretty well. When it was empty and we towed it home from the dealer it wasnt very stable. It did require a bit of fine tuning once loaded.
A travel trailer is an entirely different beast from other type trailers. The high profile and surface size make it easy for the winds to move it around.
I believe you just need to go back through the setup manual on the hitch and start from scratch.

Neil, That is the brochure tongue weight. I see that one can purchase a scale, but to tell you the truth, I have spent a bunch of money buying extras to be able to enjoy this unit and am about spent out. Is there an easy AND economical way to calculate this?
We did the measurements in the drive way, which is not paved. I think we are going to try it again with some boards on the ground (OSB or Plywood) to get more accurate measurements.
Anybody out there close to Fayetteville NC with a scale I could borrow?
Bill

You can find local scale (like a truck stop with a cat scale) you can weigh the truck with and without the trailer to get a pretty accurate weight of what's going on. This will cost you a little money (you can get 2 weighings the same day) but it's usually under $20. Others here will chime in on the way to do it and cost. I am lucky to have a truck scale at work that I can use.

I have a tongue weight scale, but with the fifth wheel it's not as easy to use so I instead use a CAT scale at a truck stop. The one by me is$12.50 to weigh and then I think a dollar or two to reweigh within some amount of time. I've also heard of people using scales at landscaping suppliers or even some truck weigh stations supposedly leave the scale turned on when they are closed (I've never done this I'd certainly call and ask someone).

You'll want to weigh once hooked up and loaded to camp. Then unhook the trailer and weigh again with everything else in the truck the same.

This should allow you to bank into the trailer weight, tongue weight, and truck weight. With those numbers we can get a better idea what's going on. Like the others I'd bet you'll find you're low on tongue weight. I'm this case a tongue weight scale could be a good investment so at home you can see the affect of adding or removing water, or loading or unloading compartments. I have also seen a way to measure the tongue weight with two bathroom scales, but I've never done this. This is the scale I have:

Bill,

We tow a 2600RB and I'm certain that unless your trailer is empty, 4 washers is not putting enough load on your bars to contribute to any sway control. Install 5 washers and replace all four of your shocks since they are most certainly wore out. Also keep in mind, shocks do not support weight but simply dampen input to the suspension system.

Do these two items first then when your TV tires wear out, try to find a nice set of D rated tires. I installed E rated Michelin Defender tires which are great but they are too much tire for the load being carried. I air up the fronts to 45 psi and the rear to 50 psi and air them down to 40 psi when empty to try to regain my original ride quality. Also the much heavier E rated tires will cost you about 0.5mpg off the top.

Different hitch but similar concept on my 2600RB. I have the maximum number of washers I could fit on the tilt pin on my ProPride, and when I'm loaded for camp, I'm actually adding weight slightly on the steer axle. I just swapped out the P metric tires for some Nexen RA8 AT Pro LTs and the first tow with them this past weekend was a true torture test. 40 MPH gusting crosswinds. Zero sway. None. I was getting moved a ton in those winds and sawing at the wheel like a Nascar driver who needed new rubber 8 laps ago, but the tires didn't have that squishy feel the P metrics did, and the ProPride held the right straight and true.

I have an equalizer with zero sway so they can be set up to deliver. And it was only $500.

Update: Fully loaded for a one week trip and with full water, my 2600RB tongue weight is 960lbs.
