- We looked at stacking, top blocks and handles.
- Value
- We weighed price per piece.
What Matters Before You Choose a Leveling Block For Triple Axle RV
Key buying criteria so you get the right fit the first time.
Count the blocks you need
A triple axle often needs two or three stacks per side, so a ten piece set may only build one ramp. Count the blocks needed for your tallest lift times the number of wheels. Check the pack count and whether tops are counted.
Footprint under the tire
A longer block like the 17 inch Camco spreads the tire load across more material. Small blocks can sink on soft ground. Look at the length and width in the listing.
Interlock and top blocks
Interlocking blocks stop the stack from sliding under load, and top blocks give a flat finish. Without a lip the tire can roll off. Look for interlocking in the title and top blocks in the contents.
Load rating honesty
Several listings do not state a per block weight rating, so match the material and brand to your weight. Do not stack beyond what the maker allows. Check the listing for a stated capacity.
Storage and carrying
Blocks add up to a bulky bin in a storage bay. A bag or T handle makes carrying easier. Check whether a bag is included.
