Suction by big trucks is normal, sway is not.
Start with properly weighing the setup and start comparing our against your truck’s ratings.
You specifically want to look at:
- the tongue weight percentage being between 11-14%
- the rear tires of the truck not being overloaded
- the front axle of the truck not being significantly unloaded with the WDH engaged
And take your WDH owner’s manual with you. Adjust it at the scale, most dealers get it wrong.
But it all starts with weights:
Once you have the 3 travel trailer weights, run them through the TowingPlanner’s Actual Weights calculator.
