You could check the brochure archives at Winnebago. It should be noted in the 2019 brochure.
Oh, I see the archives don’t have towable. But the internet does:
FYI, your TT is not a MMW… that would be a Micro Minnie Winnie. No such model. Winnebago’s model names are so close to one another it’s best to be careful with model descriptions. Not scolding, honest just pointing it out since you’re a new owner.
Micro Minnie - TT (Yours)
Minnie - TT
Minnie Plus - TT
Minnie Plus Fifth Wheel - 5er
Minnie Winnie - Class C
Micro Minnie Winnie - a “player to be named later” no doubt
