looking for a specific floorpan

Well, hallelujah! I finally found what appears to be a great travel trailer with a great floorplan for my needs. It is a 2016 Open Range 308BHS. I am the second owner and the quality of the manufacture appears very high. I had to correct a couple of deficiencies, but they were mostly minor. The original owners were a couple who used to camp with their sons, but, as usual, the sons grew up and developed other interests so they were downsizing. The couple were extremely nice in pointing out the minor discrepancies and I've got most of them corrected. There is one thing, however, that I could use the RV community's help on: the seating arrangement is a very nice, extremely large couch that has two small tables that mount on "monopoles" that wobble excessively. In spite of trying to tighten them up, I think the design itself is the problem because every small "looseness" in tolerance is exaggerated until the wobble/shake is excessive. I noticed that the base is actually mounted on top of the carpet, which, by itself inserts some "looseness". Just wondering if anyone who has faced this has found an aftermarket "fix"?
