Where to place jack to change tire on Toy Haulers?

Assuming that I have only a single bottle jack and I want to put jack stands under both axles (of just one side), how would I go about that? The general consensus seems to be that placing the jack (bottle or stand) under the spring perch is the way to go. There isn't enough room to jack up an axle and then get the jack stand under the same spring perch.

I'm certain that without a LOT of cribbing my bottle jack won't reach the frame.
