Cap Concrete Block RV Pad
Has anyone used the Cap Concrete Blocs to use as a Pad to park the trailer on? I wanted to make it big enough to just put the tires on and off the grass. Cap Concrete 3.6" x 7.6" x 15" wide O...

The cap blocks do not have any aggregate in them and are very weak. You can prep the ground sufficiently with thick layer of stone and then place the pavers. They may last depending on your location and subsurface preparation. Plus they allow grass to grow through the cracks. Grass under the RV while being stored is a no-no (so I've heard).
I am a civil engineer (my license is in geotechnical). Your subgrade (dirt below the pavement profile) is the most important factor in determining how long your pavement will last.
If I was doing an area on my property, in the Alabama area, to support a parking load of an RV with a weight of about 14,000 - 20,000 lbs, I would first have about 12" of compacted soil (non plastic clay/sand mixture - this is typical in my area). Then I would place 4" of crushed stone. Then a minimum of 6" of 4,000 psi concrete.
Remember that you will also be stopping, starting, and turning on the pad. This adds additional forces that will impact the soil under the stone and concrete. If the soil under the stone and concrete is not prepared properly, potholes and rutting will occur.
