We started with a pop-up, then TT, then a summer home, now a Class A. It's older but we only use it once a year, Michigan to Florida and back.
You have a decent tow vehicle so that's a plus for going with a TT, less outlay to start. You also don't need to tow another vehicle so you can do some site seeing. Personally, I think that's where the advantages of a TT end.
As mentioned, a motorhome doesn't require any setup if you're just stopping for the night or the weather is bad. If the weather is cold, the MH is already warm when you stop, hot weather it's already cool. No waiting for it to get comfortable. Traveling, the wife can grab me a cold bottle of water from the fridge, make a sandwich, use the bathroom without stopping.
Is there more maintenance to a MH, sure. It's another drivetrain plus license/registration, insurance. Is that added cost worth it, that's up to you and how you'll use it. For me it was but I do almost all my own maintenance, I'm retired so I have the time.
