2x Blocks Under Jacks Reason??

My understanding is that some folks put blocks under the leveling jacks to have less movement inside the rig. The theory is that since you're not running out the jack as far, it makes for a more stable platform.

As far as the coveralls and gloves...yuppie city slicker.

In addition to keeping the jacks shorter, the blocks usually have a larger footprint and do not sink in to the ground as much, therefore the setup is again, more stable. So they are not doing anything wrong, maybe just a little more fussy. I bet they watch you and think you are a rookie! lol.

The footprint of our HWH kickdown jacks is very small. Unless the site is paved or very compacted, they'll sink in.

By drilling a 1/2" hole near a corner I have a way to move the 2x blocks around with my awning rod.?ñu

You should be using blocks or jack pads of some kind to prevent damage to the RV park pads. The is especially true if the park has asphalt pads and even more important if it's asphalt and quite warm outside. If you are on concrete and you are going to see freezing temperatures the jacks can freeze to the concrete crippling your RV had you had plans to leave. At least with blocks you could raise the jacks and beat the blocks off.
There are a number of reasons to use them and very few reasons not to.

Guess them folks aren't so ignorant or just know better. :B

Jacks will be less likely to freeze to the ground if that is a concern.

Soft ground and inadequate jacks would be one reason to do this. If the jacks sink into the ground they won't level anything

This is a very good answer.

Placing blocking under any jacks can increase the overall foot print of the jacks. This reduces sinkage into the ground or even asphalt pavement.

The small foot print of the jacks can easily punch right through asphalt, sandy areas, gravel or just plain dirt.

Blocking or even 2x10 or 2x12 cut into 1ft lengths will create a stable platform for your jacks to sit on. This also reduces the amount of times you have to relevel or mess with your jacks after heavy rains...

Folks are smarter than you think...

You gotta watch them ignorant yuppie city slickers, some of them just might teach you something.:)
