I use those exact cables on my trailer. They've held up well. I went with them vs regular quick-fit chains due to clearance to the shock mount. I suspect SCC recommends them for your van due to similar clearance constraints.
They've held up fine on my trailer, which is loaded up to about 6,000 pounds per axle. I've probably put over 5,000 miles on them. Basically, I use them whenever the chains-required signs are up.
As long as you don't spin your tires, they should hold up fine for you.
On the van, I use Heavy Duty quick-fits from Les Schwab. They look like this:
My rear axle weight close to 8,000 pounds when loaded with the trailer, which is the only time I use them. Total combined weight is around 22,000 pounds. The chains only go on the outer duals, so they don't have as much weight on them, but they do all of the tractive work. Probably IMO overkill for a Sprinter, especially one that doesn't tow. But they work very well so they could be a good option if you'll be going into deep heavy snow (like off highway trails, or even mud), assuming you have enough clearance.
