Weight question

Thank you all for your advice. I truly appreciate it. I don't have much experience with towing or mechanics but my husband was an OTR tractor trailer driver so I am confident in his towing capabilities. He has mentioned multiple times wanting a TT so this is going to be a surprise for him. Hence why so many questions. He is a wounded warrior battling PTSD and doesn't like to get out and do anything where there are crowds. Figured this would be the perfect activity to do as a family that would let him be in a comfort zone in smaller camping/rv parks with the ability to go to his space (in TT) if needed. Think we have decided to upgrade his truck and then I will surprise him with a TT. Again....thank you all.
