Yes,

Traveling quite often in the south during the summertime there was no way I could get away with no coach AC.

I basically followed this procedure with some differences.

1. Made three cross members on roof top of galvanized u type metal.

2. Placed 2"X2" blocks under each end of metal cross members so could raise center of roof an extra 1/8" for better water runoff when rv is sitting level.

4. Ran galvanized 5/16 carriage bolts from starting  inside though the new wood cross members, through the existing roof cross members, through new U-metal cross members.

5. Sealed carriage bolts holes on rooftop with silicone sealant.

6. Coated and sealed entire rooftop with :

Though it was not a simple fix it was a professional fix and it came out just great.

Thanks, Ed! I'm not quite ready to tackle this project just yet (working on installing a solar system first) but you're instructions are incredibly helpful. 

Last question (I think:-) - Did you place the galvanized u-type metal pieces on top of the existing/original aluminum framing in the roof?
I haven't reached out to Winnebago yet but I've been told that they will send a diagram of the framing upon request.  My thinking is that if I utilize the existing framing it will be stronger than just drilling through the roof.

Stripper pole, that's funny.

I'm going to get some pole jacks from home depot and experiment with them.

Thanks for your help.

Did you end up fixing the sag with this method? I also have a '91 Spirit 321RB and have been trying to figure out the best way to address the sag caused by the a/c unit. I've removed the a/c and replaced with a Maxx Air Vent Fan and the sag remains. If this worked for you, I'd love to see pics of the process.
