slides first or stabilizer jacks first?

I do it which ever way it happens. I figure the slides are deployed in the dealers lot for long periods of time without the stabilizers down, so the frame can obviously handle it. But with four of five people moving about inside it may be a different story over the long term. I agree putting the stabilizers down first tends to over burden the slide side while the other side floats in mid air, so you'll probably have to readjust later anyhow. Prolly slides first then stabilizers would work better but I doubt it matters much.
