I think you'll find pavers do not work for a MH pad. The ground will settle under the pavers where you drive it and even more so where it sets and the pavers will soon be kicked up at odd angles all over the place.
Why is it then that many upscale RV resorts use paver pads for their sites? A proper base is necessary for either concrete or pavers. The good thing about pavers is that they can be easily fixed if there is a problem. With concrete, once it is cracked, it stays cracked.
