"the Payload is only 2180lbs (in my case 1950lbs according to the Door Jam Sticker)." I'm sorry to be the bearer of bad news, but that is for the front AND rear total. When you put an 80 pound dog in the front seat with you then that 80 pounds is subtracted from the 1950. If anyone (like an RV salesman or Dodge salesman) tells you differently they are simply wrong.
There are a couple of "told for truth" ways that your door sticker is configured. One says that it is including a 150 pound driver and a full tank of fuel. Of course the other says it is dead empty with no passengers/drivers and no fuel. You can take your choice, but either way you have very, very little leeway.
Again, I'm sorry. I wish I had better news. But kudos to you for wanting to be informed.
