pavers (to park our RV on) (NE PDX 75th/Prescott)

Hi! A friend is letting us park our RV in her backyard where it is currently all grass. Not planning to do the whole length, so just looking for enough pavers to put under each tire.... but will gladly take whatever amount you have. I have a flexible schedule and a truck I can borrow anytime so I can pick up at your convenience. Thanks!
