If you have a Roadtrek, you might find it too low to get under unless you are very "trim". The side pods and front skirting are quite low.
Drive on blocks are often the easiest for folks, but personally I prefer using floor jacks and stands, so the wheels hang free. Much easier for greasing, as you should have the wheels hanging to get grease into the ball joints, and you want to be able to turn them besides. 11 grease points, as Marko says is what is on our 07 190P. The one folks usually miss it the one in the near top side of the idler arm. On stands, I can get a lot of room underneath. You need 3 ton rated stands for sure, or more.
A 3 ton jack will lift either end of the Chevy, it is what I use. But, to do it the best, I use two of the jacks in the front because Chevy has removed the center of the crossmember as a jack point. This makes lifting one end at a time near impossible. I use a jack on each end of the crossmember, so they each get 1/2 the load, and the frame is stronger there besides. It works very well.
