i used a tow dolly to pick up my parts car, and the car almost rolled over a hill into the woods!
car was on a slight hill next to the woods, put it in neutral and tried to push it up, car wouldnt budge. forgot car was in neutral. disconencted the tow dolly from the truck (my first time towing and i couldnt really back up too well with it attached) push the tow dolly to the front wheels of the car, and upon imapct car starts rolling over the hill (only moved like 3-4 ft before the seller jumped in and hit the brakes. used the truck to pull it abck to level surface, then tried again. got it on the dolly using a come-a-long. took about an hr total to get it hooked up!
then i drove 425 miles home!
