Agree on the walkie talkies! Having the passenger get out and direct you in, one piece of advice my sister gave me was to have passenger guide stay middle so you can see her, and just slowly move the MH back dead middle of her. Keep it middle all the way back. Works well.
Go to YouTube and there are plenty of advice on every subject, and ask for help when you need it. People are always willing to help. Practice, read, and practice!
One more piece of advice, learned by my husband, IF IN Doubt, GET OUT and look, check for trees, cars and misaligned shore power hook ups that stick out, and rocks.
Have fun! It's addictive!
