  • It is a strong box.
Size: Single
Not much to say, other than it is holding up the RV (weight at ball of RV ~ 600#). Easy to pick up and store while traveling.

  • Bought 2. The best!
Size: Single
Couldn’t find a suitable substitute at any local stores. These are the strongest and best! Makes using our electric tongue jack faster and easier. Especially because our driveway is sort of steep for parking our trailer to load up for trips. Must have item!

  • Initial thoughts
Size: Single
I can already tell I’m going to like this! Less of the Jack is exposed, less effort to crank up and down. The block itself is molded well and seems very durable!

  • Awesome
Size: Single
So much better than the wood scraps we were using. Super solid and heavy duty really well made

  • Great blocks
Size: 5-Pack
I’m super happy with these they handles the weight and distributed the load well.

  • Great
Size: Single
Seems to be exactly what I want.

  • Heavy and Cumbersome
Size: Single
Over all like the product. Well made and does the job. Only complaint is it’s heavy and cumbersome to use. Perfect for a seasonal use or storage but not so much for overnight or shorter camping trips where you’re moving every few days or weeks.

  • Great product!
Size: Single
I bought two of these because we liked them so much! Great quality and very strong! This is a much better storage option for you to leave your trailer jacked up on. As an avid camper I highly recommend 👌
