2020.. 2108DS Jacking/support points

[outthere]

I want to change all four tires at once on our camper.
I hope this is ok to do... if not, then one side or one axle at a time then.
Are there some good posts and pictures with jacking and blocking points referencing our unit?
I have firm ground, floor jack, 6x6 and 2x lumber.

Thanks,

Steve
