Steps To Block Up A Fifth Wheel | A Permanent Solution

Although it might sound like a lot of work blocking up a fifth wheel, in reality, it isn’t. With a bit of muscle, precision, and safety, you can turn your fifth wheel into a stabilized permanent resident. In order to do this, there are a couple of things you will need.

Things you will need:

  • Cinder blocks.
  • Plywood/wood planks.
  • Level.
  • A jack (optional) 

Step 1: Make Sure It Is On Level Ground

The first thing to do is make sure that the RV is on level ground. Use a water level to check the RV if it is. Then make sure the fifth wheel is also on a level ground. 

Step 2: Place Cinder Blocks All-Around

When everything seems good and leveled, start placing cinder blocks all around the RV. Make sure they are under the frame, not the body. Place them 7-8 ft apart.

Step 3: Place Wooden Planks Or Plywood Along With The Cinder

When you are done with placing the planks, make sure you install some plywood or wooden planks on top of the cinder block. Let it work as a barrier between the RV and the cinder block so it doesn’t damage the frame. 

Step 4: Reinforce Extra Blocks And Planks On The Fifth Wheel

You have to make sure that the fifth wheel doesn’t tilt around. So place some extra cinder and planks under it. 

And you are done. Now your fifth wheel is all blocked up. It’s not going to move. 

Note: Use a jack to lift up the frame of the RV so the cinder and wood planks can be placed perfectly. Do not overcrowd with cinder though, as it might damage the chassis.
