For us, we have had our little mishaps. Just remember when using a spotter, make sure your communication is clear. I told my daughter once "Let me know when I get to the tree" Guess what, I got to the tree, stopped when I felt it, a little dent in the bumper of trailer, no big deal. Also scraped the house with the awning rail cause I was to lazy or in a hurry to wait for Karen to help me out. What ever, do what you got to do, be aware of your surroundings, get out and discuss with you spotter your plan, and make sure you can see them at all times or get out and tell them you can't see them. Good Luck & Be Safe ! ! !
