2015 navigator towing 29' trailer

Moved from Forum Technical Support

Depending on road conditions and wind I'm limited to 60 to 65 MPH to still feel in control

You should limit yourself to that in all conditions, always. Most trailer tires are only rated to that.

You're always going to feel some movement with passing trucks and gusty winds, no matter what you drive, but there are things you can do to minimize it.

A longer wheelbase vehicle would be best but I don't imagine you want to get rid of a new vehicle. Ensure you have sufficient tongue weight (~13% of tt weight) and the hitch is set properly to transfer enough weight back to the front of tow vehicle.

Air the tires to the max rating. If you have P rated tires (soft squishy sidewalls) consider getting better truck tires with stiffer sidewalls and higher ratings.

Short Wheel Base (I am there with my setup) and P rated tires and soft suspension could be all contributing factors to your wiggle. If you have the 20" tires, I only see one LT tire in your size.

Not saying this is definitively the issue, but you could be seeing the impact of a small wheel-base. The 2015 Navigator has a wheel base of 119". Here's a good article of the impact of wheel base and the size of the travel trailer.

Im not saying this IS your issue, but something to consider. If you assume the article is relatively accurate, it basically says the first 110" of wheel base is sufficient/accommodates a 20 ft trailer. For every 4" above, you're good for another foot in TT length. So, if you assume this is close to correct, your trailer exceeds this "formula", by 7 ft. Now, Im basing that comment on the title of your thread (29ft trailer), not the trailer model (22FBS), which I assume, in reality means the box size of the TT, not overall length.

Again, not saying this is the issue, but could be.

You might get better response by asking the moderator to move it to the "Towing Forum." You are now in "Forum Technical Support."

On the top right side of your post is a button where you can contact the moderator and ask.

Happy Camping.
