Read your manufactures operating instructions. Our Newmar book specifically says to level first. When you think about it it seems to me to be logical that this is the correct procedure. Extending slides with the body in a twist just doesn't seem logical to me

Snail1,
That's very true. BUT... in this case, "the manufacturer" (Newmar) is saying one thing in the manual and then telling customers another thing in person.
And, while the chassis is aired up, I don't think it is any more likely to be "in a twist" than it would be when "leveled" on the hydraulic jacks. Now, obviously, you CAN torque the chassis while the suspension is aired up (shallow-angle of approach across a steep driveway entrance, for instance), but I doubt most people are in that situation while parked in an RV space ready to put their slides out.
I think it is also just as easy to torque the chassis by leveling. If you are in a severely un-level space, you can inadvertently extend one or more jacks to their maximum travel. If the opposing jack is still able to extend, you can end up twisting/torquing the chassis. Or, even on a reasonably level site, you can end up torquing the chassis as a result of lifting one end/side while the other is resting on the chassis stops. Being "level" doesn't necessarily mean you haven't twisted/torqued the chassis.
Certainly... you can't be held at fault if you "did everything by the book" and followed the instructions in the owner's manual. But I also don't always believe everything I read!
