I have a 09 Tundra that I did not get the towing package on but I am wanting to buy a boat here very soon. I know that the bumper is rated for 5000lbs but I am now wondering about intalling the 2-inch ball correctly. The owner's manual just says to call the dealership for installation. On the bumper there is not any holes to install the ball but there is indentions in the platic area where the ball would most likely go. I may be a little precautious here but I just want to do this right and not damage my truck or soon to be boat. Comments? Ideas, etc?
