Height of trailer with lift kit + 15'

I'm sure this is somewhere on this forum, but I cant seem to find it.

What is the difference in height when adding a lift kit plus 15inch tires? My 2000 3023 is currently 80" tall closed. My garage door opening is 83". So, if I add both to the trailer will it still fit?

Also curious what this "lift kit" looks like. Does anyone have some before and after closeup photo's from under the trailer? I looked up under mine, and I am wondering if the previous owner added this lift kit, and all I would have to do is get the 15" tires/wheels.

Thanks for the help. This forum is a lifesaver.
