What do you DIY'ers use to jack and secure your rig?

For changing oil and anything quick and easy underneath, I roll the MH up onto some wooden blocks, both front and back so that it sits level in the street. With the Fumoto valve and the truck size oil pan that rolls underneath, I can drain the oil and replace the filter in less than 10 minutes....than I just add the fresh oil on top. Anything major, I use 20 ton Hydraulic jacks(x2) and truck Jack stands.
