Bunkhouses similar to 272BHS with light hitch weight

The camper will have 800 lbs of tongue weight when it is all said and done - regardless of what you say in your post - that's just the reality. So you will be at max payload with your suburban (there is nothing wrong with towing at max). End of Story.

For the record, you don't want light hitch weight. Light hitch weight equal "SWAY".
