I'm slowly building up my jeep accessories and now is strap time. What are the suggestions in terms of pound rating, length, brand, etc. I also will need a tree strap and 6 foot seems to be number, but again rating, brand, etc. As for shackles, I plan to just keep 2 mounted on the front bumper and they could easily be moved to the rear if needed. But I'm thinking I should keep a spare or spare pair. Thoughts? Again ratings, brands, etc. All input is appreciated.
