Welcome to both new members. Seems like there's a similar history to most of us a-framers: long-time tenters needing something more comfortable. You'll have a blast! We're about to start our second year in ours; just pulled it out of storage today. The weather's been great, I hope I haven't jinxed it by getting Rocky (as we named it) out.
To the question of needing a special hitch, I pull my unit with a 12-year-old Chevy half-ton pickup, using just the towing package that came from the factory. No wdh or sway bar. It's shown no tendency to sway nor is the hitch weight excessive for the TV. Another member does use a wdh because the TV is a Jeep. So go with what your TV manual says. Peace of mind with your precious cargo aboard is priceless; the right hitch combo for your setup and a good brake controller are a small price to pay, whatever they cost.
It's never too late to have a happy childhood!
