Difficulty Reducing Tongue Weight

Hello! I joined today because I have been unable to solve my towing issues and would like to see if anyone can give me ideas to help.

Tow rig: 2018 F150 Lariat Crew 4x4, 3.5L max tow
Camper: 2007 Gulf Stream Innsbruck 24RKL
Background: For as long as I’ve owned this camper, towing with two previous GM trucks, I’ve never felt comfortable towing this trailer. It doesn’t sway, but in any type of winds, the stability just isn’t great. It feels as if I am being shoved around and it can be difficult to keep in the lanes at times. I upgraded to an equalizer hitch setup in hopes that would help, but it has not. I decided to start from scratch and start weighing everything. This is where I ran into a serious problem. My camper, with no propane, water, gear in the front is weighing in at 1200 tongue weight using a sherline scale. After finding that, I hit the cat scales and confirmed a reading of 1160. This is well in excess of the recommended 10-15%. I am also just under my gvwr, with just me in the truck, and the tongue weight is over the rating of my equalizer.

I tried to fill my back grey tank, shift weight and the best I could get down to was 1100 lbs. Basically, I’m at a loss on how to get this trailer down to an acceptable tongue weight of say 900 lbs. The actual tongue weight is far in excess of what the trailer spec sheet shows. I guess shame on me for not figuring all of this out earlier, but I want to figure out how to make this safe and comfortable to tow.. I would appreciate any suggestions, and please let me know if I’ve left out any detail needed. I am looking to get rid of this camper at this point because it would seem that I need 600-700 lbs of ballast at the rear to make this right, but I am afraid of creating a sway issue. Thank you for any and all input.

    Your problem isn't the truck, replace your trailer tires. go to (G) or heavier
  • Is there any way you could try towing the trailer with a heavier truck, like a 2500 or an F250, or even a dually? See if you experience the same things. My first guess is, the truck itself is just too light. It may tow the weight, it may also be within specs for load capacity, but the actual weight of the entire truck is just too light, trailer too long, and trailer too heavy. The weight, design, and length of the trailer just overpowers the truck, causing very uneasy feelings when driving. If you can borrower someone else's truck for a short while, go for a drive, see what you think. If you still experience the uneasiness in the heftier truck, then something is wrong with the camper itself. That's the approach I'd start with. Good luck.
  • I thought about that as I have the 1000 lb bars since the tailer is supposed to be around 900. At 1160, I am at 17% tongue weight. With the setup now, I have the front truck tires at the exact ride height as they are when I'm unhitched. All along I thought I had too much weight removed from the front steer axle causing this issue. Unhooked, front axle is 3180, hooked no WD its 2700, hooked with WD is 3040 lbs.

    I just don't see this being stable at 17% even with heavier WD bars because that won't change the static tongue weight down from 17%. Here is my weight readings:

    With WD Without WD Truck (GVW)
    Truck Front Axle 3040 2700 3180
    Truck Rear Axle 3900 4420 2780
    Trailer Axles 5840 5660 N/A
    Gross (GCVW) 12780 12780 5960
    Truck Weight GVW 6940 7120 5960
    Trailer Tongue Weight 980 1160 N/A
    Trailer Weight 6820 6820
    Tongue Distribution 14.37% 17.01%
    Ideal Tongue Weight (10% TW) 682 682
    Target Weight Shift (10% TW) -298 -478
    Ideal Tongue Weight (12% TW) 818 818
    Target Weight Shift (12% TW) -162 -342

    2018 F150 Pkg Specific GCWR 18,100
    2018 F150 Pkg Max Tow 12,700
    Under/(Over) GCWR 5,320 OK
    2018 F150 Pkg Specific GVWR 7,000
    Under/(Over) GVWR 60 -120
    Camper GVWR 7960
    Under/(Over) GVWR 1140 OK
  • You probably need a stronger set of bars on your WDH (or adj them tighter). You do not want to lighten the tongue - that is a common mistake and will not improve handling.
