While towing a 2000 lb-16 ft boat, my Odyssey sways with subtle steering movement. I feel unsafe driving this vehicle while towing. My 2005 Sienna had no such issues. I increased tire pressure by three pounds. There was little or no improvement. The boat trailer is not the problem as I have towed this rig behind many vehicles and it tracks great. This vehicle is rated for larger towing loads and that is scary.
