When using stands, you always want to get under the frame rail when ever possible. This is the strongest and most stable point and once seated and stable, the coach is not coming any lower.
Wood blocks are more difficult to place safely. The frame is the safest place but is very high most times and requires a very high pile of blocks which can become unstable. Under the wheels is your next best place (I think) if you can get them there with the coach unsupported. This way you can judge better how much minimum clearance you have.
I don't say this being ugly, but if you are not certain, take it to a PRO and let them do the work. Not worth getting crushed to save a few bucks.
