Unless you AND your DW are already experienced and comfortable driving a full sized pickup in city traffic and parking it in tight Walmart parking spaces, I highly recommend you consider a mid-sized pickup or large SUV rated for your TT. On vacation, you will spend more days driving to sightseeing and shopping places than towing your TT. When not on vacation, will you park/store the TV along with your TT? No, you will be driving it to work and shopping not towing.
My DW and I have been VERY HAPPY towing our 30ft 7000# TT for more than 30,000 miles in 4 yrs with our Canyon.
