What Jesus said plus either timbrens or airbags for the rear. Suburbans are saggy as it is. I wouldn't bother changing the axle. It's the engine that will be your limiting factor. Not that it won't do it, just obviously won't be as great as a BB or diesel. Towing in Michigan will be ok, but a trailer that big in the mountains and you will be hating life.
