I Was was testing my 02 v10 with my 24' camper behind it and it was windy and it felt like something was pushing on the back end when the wind would hit sometimes and it was harder then it should have been to keep it in a strait line. It wasnt quite white knuckle driving but not great either. I have RAS on the back as well as the Hellwig sway bars set on the max on both i have new procomp 9000 all around and new front sway bar bushings. The hitch is a weight distribution hitch with a anti sway bar on it. Will a set of v's up front help eliminate this problem? I like how the excrusion rides stock and dont want the lift that comes with the v's. How much stiffer of a ride does the v's give the v10? is its just slightly stiffer? or is it noticeable how much rougher it rides? Will this solve my problem or is this just a aerodynamics thing sense the excursion has so much area for the wind to hit?

 

What you are describing is a sway issue, not a wandering issue. Most of the problem probably lies with the hitch and trailer, not the Excursion.

Since it is a sway issue, I would really like to see a picture of your WD Hitch setup and attached.
Also, if you can get to a certified cat scale at a truck stop, the weight of the front and rear axles of the truck and the trailer axle weight would be a big help in figuring out what can be done to help.

 

This is the setup i have right here. Dont got any pics of the setup sense i already put the camper back.

As for the weight i can do it later but i never had any of these issues with my f250 sd on 37's and 5 inches of lift with the same trailer and hitch with out the under bars hooked up.

 

There is a huge difference between your f250 and a Excursion in one respect when it comes to towing.


The Excursion starts out with 1400lbs more weight on the rear axle. This means a big difference in how the WD hitch is able to handle the load. you see, the WD hitch is not only trying to lift the weight and level the tongue, it also has to deal with lifting the extra weight of the rear of the EX. This requires extra care when setting it up.

 

That makes sense. The trailer was empty when towing it and 55 psi in the rear tires.

 

Is it the Sportsman S242SBHSS (slide) or S242BHSS?

 

Its got the slide.

 

That makes things even more interesting. That trailer is fairly lightweight for the EX. I agree it should have no problems towing that empty even without the WD bars hooked up..

When you say it was empty, was there anything in the water or waste tanks? Where are the tanks located? They look like they are in the rear on the floor plan.

 

Nothing in the tanks and didnt have the batteries in it too. I normally drive with the water tank full and it at the back

 

The reason that I asked about the tanks is that a full tank in the back can unload the tongue weight enough to be below 10% of the trailer weight. Too little tongue weight is one cause of trailer sway, but not apparently in this case.

I use this effect of water in the back tank to limit the tongue weight of my trailer (2010 Jayco 322fks) to 1250 lbs or under.

I take it the friction bar is in good shape and the pads are fine and trailer tires are inflated evenly?

 

1,400 lbs heavier in the back Bion? I don't think it's that much.

Mine is 3,750 lbs on the rear axle with a full tank of fuel, and both my Super Duties were north of 3,000 lbs in the same condition. And I disagree that this has much bearing on the WD setup; it's only responsible for managing the weight transfer with the addition of tongue weight. The excess weight we have compared to the pickup trucks doesn't have much bearing on that.

Completely agree about the trailer setup being paramount when considering sway. The OP should weigh the rig to ensure he has ~10% on the tongue. I installed v-code springs on mine and never noticed a difference in trailer stability. Proper tongue weight makes a night and day difference though!

 

Its was empty so it should have been setup pretty well. Im thinking that it was just the fact that there was more area for the wind hit on the excuraion vs my sd

 

I wonder if that's an issue. I don't even run that low when I don't have a trailer hooked up!

 

I do got to say going from the diesel and manual to the v10 auto im extreamly happy with how it runs with the 4.30 gear! The only thing that sucks is the mpg but i expected that. The v10 sounds a million times better then my diesel ever did

 

What psi do you reconmend. I use to run that with my 37 but that was a wider tire so it didnt need as much air to get the same lift
