Hi all,
Thanks for all your feedback. I guess I didn't elaborate enough. The tow rope broke about a foot from where it was attached to the F150 - it had not been wearing on any part of the truck or rubbing on the ground. When it broke we were in my friend's driveway that was about 30 degrees incline.
**Update: I decided to buy the 6"X30' tow strap with loops from tractor supply - it is rated at 55,000 pounds! I know it is probably overkill but at least I can be 99% sure it will not break this time! Now I am wondering if I should buy any hooks to go with it? Or should I just make the loops work?**
