You might add your tow vehicle and the TT with model number to your signature line. It will help people answer your questions without having to ask and it will also let people know what you have when they have questions about a similar rig.
Just go to the USER CP tab at the top of the screen and then look around for the EDIT SIGNATURE tab.
Not sure of the door rating for the Suburban, in 2022, it was rated for between 7400 and 8300 tow capacity. With a 5K dry weight, you may be pushing that. Payload is between 1539 and 1750 pounds. Figuring with a dry weight of 5K you have an actual weight of 6K, and 12% tongue weight, you have used up half of your payload with the TT.
Good news is the Suburban is longer than the Tahoe, so a much more stable tow vehicle in that regard.
Your rig may be pretty sensitive to setup, the WDH as well as determining what goes in the trailer, what goes in the Suburban. (Hint: Kids, Spouse, Pets in the Suburban, cargo in the trailer. )
