I have a 20' cargo trailer and it weighs 3000lbs empty. You should be fine with that as I doubt you will have more than 2000lbs of furniture. The issue that you may have is that the tongue weight on my trailer is over 600lbs empty. I would suggest putting the heavy furniture towards the rear to keep the tongue weight around 500lbs. Without a tongue scale, you won't actually know if the tongue weight is correct though.
My 20' cargo is about 3500 lbs dry and rated 10,000 lbs. Typically I am loaded up between 6000-8000 lbs with close to 1000 lbs tongue weight. You will be at the limits of your motor home but should be close based on the furniture you are carrying.
If you have not bought the trailer yet, look into aluminum frame versions which will cost more but be 500-1000 lbs lighter for the same weigh rating.
I did a round trip NC - WA trip last April to clear out an estate and was carrying about 2500 lbs of furniture and household goods in my trailer, yet I was only loaded up inside less than half high.
