Traveling back from a Points Regatta in MI years ago a piece of firewood was laying in the middle of the Hiway. My wife centered the car over it. The front of the car missed it but the back of the car was lower. The car lifted the firewood enough to "center punch" the trailer axle. Instant toe in to the extreme. Wore the tires bald getting it to my Uncles place. I went back for it two days later with a come along and pulled the axle straight enough for the hour drive home. Had to replace the axle and two tires.

Do a walk about, look over and under the trailer. Don't be in a hurry. Check the trailer often, especially after about 10 - 25 miles into the trip. Don't back the trailer into the water, use beach wheels and get buddy bearings. Always carry a spare tire.
