We just got a new pop up trailer and pull it with a toyota sienna. This new trailer when fully loaded is at the max of the towing capacity of the van. On my truck the towing tables show at what weight to add a weight distribution hitch. The van just says max 3000lb. When the weather clears up I want to take it to a flat parking lot and measure how much sag the trailer causes and how much rise I need on the hitch to level it out. So how do you determine when just air bags or helper springs are needed versus a WD hitch?
