Proper Hitch Height

[J_Ryan_2]

I have a GMC Yukon Denali with auto-ride leveling, and using Fastway E2 Trunnion Equalizing System. Once I have hooked up to my trailer, and let the load leveler balance my vehicle, equalizer system attached. Should the trailer be level with the vehicle or tilted to be slightly heavier on the tug and hitch? The hitch has adjustable shank, and it is in the lowest application point. In this configuration it appears that the trailer is level with vehicle, however I am having issues with swaying. When in High winds or HEAVY truck traffic it seems to be a BIG Hazard. I have adjusted the spacers, tried to raise the equalizer bar brackets to see if tightening or even relaxing the weight transfer with Little to NO help with control. I'm thinking that with the ride control leveler on my vehicle is causing the weight to transfer back to the trailer and not letting the sway control of the E2 System to function properly. Would it help to get another hitch shank that will let me lower the set-up a couple more inches to keep the weight on the hitch and WD System? Not VERY comfortable driving at SLOW speeds, much less at 65 mph.

I have looked into the ride control, and have not found anyway to adjust the height when towing. Any ideas on where to check would be appreciated. I just changed my tires to LT's, although I did air up the previous tire when towing. I wanted to make sure that the roll was not an issue. A few more things that I have tried is adding more weight to front of the trailer (Filled Fresh water tank, Kept liquids in Black and Grey tanks, and 3 - 5gal bottles of water). The extra weight seemed to help with the sway issues. Thus the issue with How to adjust the weight of trailer without having to carry all the extra water weight? The only way to put more weight on the tongue is to lower the hitch, right or I am mistaken. Also, I checked the trailer tires and I keep 45-50# of Nitrogen pressure on them.

You don't need to adjust the ride height of the TV. There should be a section in your owner's manual telling you how to adjust the WDH on a air ride vehicle. Mine read as followed. Drive to a level place. Unhook the TT. with the engine running, let the Vehicle level. Turn OFf the air ride. It should hold it's position. then you can adjust the WDH to fit the vehicle.

First measure the front bumper to the ground, Then the rear bumper to the ground. Drop the Tt back onto the ball. Before installing the spring bar measure the front again. Then adjust the WDH until you have lowered the front bumper back down to reclaim at least 1/2 of the distance it rose. Then measure the rear to be sure it is NO HIGHER than it was unhooked. Then you can turn the air ride back on, and be good to go. No need to do it again.

No just lowering the front will not add tongue weight. however it appears that you have a front bedroom, and bath. load the under bed storage with all your outdoor furniture. Load your outside front storage heavy as well. And be sure you have nothing hanging off the rear of the TT. In other words. Move every thing you can from the rear of the Tt to the front

Hope this helps.

Scales might help as well. that is a big trailer for a SUV unless it is a 2500.

Sounds like the tongue weight is too light.

terryallan and a real good question, are you tires P rated or LT. P rated will sway a lot almost on the verge of having the tire roll off the wheel. the sidewalls are too soft for TT towing

[Terryallan]

First. Do you have enough tongue weight? IF the TT is lifting the vehicle. I'm betting you don't

Have another question. When you setup your hitch. did you follow the GMC directions on how to setup a air ride vehicle? If not. there is a chance that when you start the vehicle it is rising up, and changing the weight that the WDH transfers. I had to let my TV level itself, and while level. Turn my air ride off so that it won't lower to adjust my air ride vehicle. there is a button some where. You want the TV sitting pretty level BEFORE the air ride levels it.

Next. Your TV tires. Do you air them to max when towing, and are the P tires, or LT.

And then, as you didn't say what TT you have. Is there a chance that you have more Tt than the TV can handle?

Sometimes it takes a lot of work to get it right

To answer your questions, Yes. I've gone over it several times. I have tried to change the spacer washers +/-. What seems to be the difference is the auto ride control. When I shutdown my tow vehicle and let everything go down with the weight of the trailer there is tension on the bars. After I start-up and the auto-ride airs up the trailer seems to be higher at the hitch, causing the weight shift to the back and feel like the trailer is lifting the vehicle while driving in high winds and truck traffic. The adjustable hitch shank can only drop down 4", and I was looking at a 6 or 8" drop depending on ground clearance.

2 questions - have you carefully read & followed your Fastway E2 Installation Instructions and have you called the manufacturer about your concerns? :@
