Yea, that is an interesting one, my TZ, No fear, STTNG and termi 2, are all exactly the same height, from lockdown bars to back box height, exactly.
Monster Bash looks odd beacuse it is about 1 & 1/2 inches higher at the back box.
When i had the Jurassic Park, it was higher than the Monster Bash!!!

My Meteor and Future Spa are the same height, front and backbox. My LOTR is lower in the front by about 2" and taller in the backbox by about 4". Of course, they were made about 25 years apart.
I prefer the height of the old machines. I feel the new ones are just a bit too low for me at 6'. I always have to spread my legs (easy Brokedad ) so I'm not bent over.

My freedom,BK and STTNG are all different heights.STTNG is a wide body and a heavy monster,had a lot of trouble getting it into the basement!!

Yeah, those wide bodies are a PITA to get thru doorways. My Future Spa barely made it thru mine.

scooter I had to take my STTNG 6 floors up i was quite lucky with no problems except for the weight of the machine (oh and I had to take my door down to get the pin inside)

I bet it took u a while Ice,must have been a real workout.
