I drove 2400 miles through Baja Mexico over 3 months, and used these to get my Sprinter van out of the sand 4 times. I also helped strangers get their car out of the sand; these are an incredible investment, saves THOUSANDS in towing costs!The downside is that we used them in the snow yesterday when my vehicle got stuck, and one board cracked in half. THey immediately replaced the set for me, with outstanding customer service, so I'm a customer for life.welovetoexplore.com
