Review: Excellent leveling blocks for our (heavy) Sprinter van - This review is for the FasTen XL 10 pack (10.5" × 10.5", 10 ea.). We have a 2024 AWD Sprinter van that's been fully converted to a Class B camper. Fully loaded, the van weighs ~ 8,650 lbs, and sits on 265-mm-wide (10.4-inches wide) BF Goodrich AT KO2 tires. The width of the tires were a driving factor in deciding to purchase the XL-sized blocks instead of the standard blocks. In addition, each wheel carries more than a ton of weight, especially in the rear. To be honest, I had my doubts about how well these plastic blocks would stand up to such loads. I am happy to report that after three weeks of daily use on both dirt and paved surfaces, these blocks have performed very well, showing no signs of cracking or deforming. While in use, the blocks sometimes appear to be bent (and possibly they are, but this could also be an illusion). Nonetheless, when stowing them, the blocks are perfectly flat and stack nicely for easy storage in the van's equipment box. Just knock off the dirt and pebbles, stack them up using the convenient handle, and you're ready to go.

## Questions & Answers

**Q: Why are the yellow ones $12.76 more than the brown ones?**
A: Well now the brown ones are $12.66 more than the yellow ones, see what you've done?

**Q: Why is this not a 12pk? My trailer has 4 corners.**
A: We always use more in the back anyway, but you could always buy two sets and then it will be divisible by 4.  🤷🏼‍♀️

**Q: Can these be used for storing an RV on a grassy side yard in order to keep the tires from sinking?**
A: We typically distribute the weight of our stored trailer using wide boards under the wheels and use these blocks under the crank-down balancing braces to adjust for height differences. I would guess these blocks could be used if you made a base with them. They may sink in a bit if the grassy side yard is moist as ours is.

**Q: Can these be used in colder winter months when I store my camper to keep the tires off the ground?**
A: I have my tongue on these, all year round including the NE'stern USA outdoors during the off season.  5 yrs, going strong.
