I too am 6'2" and 250lbs and have been uncomfortable in the Model 3 I have had for the last many years, I fit, but would love something more my size and so I got a used Model X this week and drove it back across country, it was a blast, but after getting it home in the first day of just unpacking and cleaning it I hit my skull on the wings more than once, and on the center support as I didn't see it with my ball cap on, I may have neck damage.
Never had an issue with the TM3, so be careful with your head. I would think I'd eventually learn, but I never stopped hitting my head on the garage door opener until we got the new door so probably going to be an issue for me.
I got the old 7 seater that is a 6 with another small captains chair squeezed in between. Would definitely trade for a bench seat version that folds down, but I got FUSC so I'll live.
