The Ultimate Buying Guide: Choosing the Best RV Jack Blocks
An RV jack block is a simple but essential tool for every camper. These blocks provide a stable base for your RV stabilizers and leveling jacks. They prevent your jacks from sinking into soft ground, mud, or hot asphalt. Using them keeps your RV level and protects your equipment from damage.
Key Features to Look For
- Weight Capacity: Always check if the block can hold your RV’s weight. Heavy motorhomes need sturdier blocks than small travel trailers.
- Surface Area: A larger footprint spreads the weight better. This prevents the jack from pushing into soft soil.
- Interlocking Design: Some blocks stack on top of each other. This feature is great for uneven campsites where you need extra height.
- Portability: Look for built-in handles or lightweight materials. You will move these blocks every time you set up camp.
Important Materials
Most jack blocks are made from high-density polyethylene (HDPE) or recycled rubber. Plastic blocks are lightweight and very durable. They resist rot and moisture well. Rubber blocks offer a better grip and absorb vibrations. Some people still use wooden blocks, but wood can rot or splinter over time. Modern plastic or rubber options are usually the smarter choice for long-term use.
Factors That Improve or Reduce Quality
Quality blocks feature UV-resistant materials. This prevents them from cracking after long exposure to the sun. A high-quality block also has a non-slip textured top. This keeps the jack foot from sliding off. Cheap, thin plastic will crack under heavy pressure. Always avoid blocks that feel brittle or show signs of poor molding.
User Experience and Use Cases
Using jack blocks makes setting up camp much faster. You simply place the block under the jack foot before you lower it. They are perfect for grassy sites, sandy beaches, or loose dirt. In the summer, they stop your jacks from sinking into soft, sun-baked asphalt. Experienced RVers often keep a set of four in their storage compartment for easy access.
10 Frequently Asked Questions
Q: Do I need a block under every jack?
A: Yes, it is best to place a block under each stabilizer or leveling jack for maximum stability.
Q: Can I use wood instead of plastic blocks?
A: You can, but wood is heavy and can rot. Plastic blocks are lighter and last much longer.
Q: How do I know if a block is strong enough?
A: Check the product description for a “weight rating.” Ensure it exceeds the weight your jack will exert on the ground.
Q: Are these blocks slippery?
A: Look for blocks with a textured or “waffled” surface. This design increases friction and prevents slipping.
Q: Can I stack these blocks if the ground is very uneven?
A: Yes, many brands are designed to interlock. However, do not stack them too high, as this can become unstable.
Q: How do I clean them?
A: Simply spray them off with a garden hose. They do not absorb water, so they dry very quickly.
Q: Will they crack in freezing temperatures?
A: High-quality HDPE plastic is designed to handle extreme temperatures without cracking.
Q: Do I need a specific size for my RV?
A: Measure the diameter of your jack foot. Ensure the block is wide enough to accommodate the entire foot comfortably.
Q: Are these blocks heavy to carry?
A: Most modern blocks are made of hollow, durable plastic. They are very light and easy to carry.
Q: Do they help with leveling the RV?
A: They provide a base, but they are not leveling ramps. Use them to stabilize your RV after you have reached a level position.
