Levelling blocks for camper on driveway with 2 degree grade

The camper jacks are adjustable. Or I’m not understanding the question.

Even if it there were not needed for the driveway, you will need them for campgrounds where the camp area is not perfectly level and flat.

You can buy a box of RV leveling blocks but they will be plastic and can easily break. I was able to find some scrap 2x8 boards and made my own. I cut them about 1' long, beveled one side and reinforced the wood with threaded rods across the grain. They have held up for many hundreds of uses. I frequently need to stack them 2 or sometimes 3 layers high so I carry 6 blocks. On occasion I have used them all but never needed more.

You say you don't have a truck.
That means the camper will be resting on the jacks, right?
Why do you need blocks? Use the jacks to level it.

However, it would make sense to put supports under the camper floor to eliminate sway as well as the side loads introduced to the jacks by being parked on a non-level surface. This will take a lot of stress out of the jack mounts.

Edited to add: of course the jacks need to rest on solid, firm ground. You can put pieces of wood underneath to distribute the load.

Threaded rods against the grain !! Absolute genius !! Come spring I will be making my own.

Also mix a little fine sand into varnish or another finish so they do not slip when stacked.

I put tight-fitting carriage bolts in that stick down into looser-fitting holes on the layer below. As you can see from the crack, I could use the threaded rod idea. Though honestly I’ve only split a couple blocks in 16 years of use.

My brother still has the plywood jig my Dad made so all the holes/bolts would line up. 1/8th inch bit for alignment, then used a spade bit to make clearance for washers and nut/bolt head.
BTW, Dad would never paint or finish his leveling blocks after he painted half the first set he made. In use, did not increase lifespan, and no paint means safer smoke when use the broken ones for kindling.

I wonder if somebody planed to leave truck camper in the driveway it wouldn't be smart to build a wedged-shaped platform just tall enough for the jacks to lower it down to? Maybe put wheels on one end, so easy to roll under after pull truck out?

I still learn something new from this forum!

Never thought of that. I just assumed my leveling planks would split apart after years of use.

You guys are too much! Hahahaha
One guy doesn’t know his camper jacks are adjustable and the rest of y’all get into the finer points of “constructing” leveling blocks for something unrelated….
On a separate note I never realized so much thought and innovation could go into some scrap lumber!

Hey Jim, Did you ever post a pic of these blocks?
