Just returned yesterday from a trip from Colorado to Upstate New York (3400+ miles), only problem found was the driver :
. Not only did the TM not sway when being passed by big rigs, even in high winds and rain, but when passing passing the big rigs. Prior to this trip, my towing adventure was approx 42 miles to camp.
Found that I averaged 13.8MPG towing with a 6cyl Chevy Blazer, and maintained 65MPH, with an occassional 70 - 75 MPH when needing to pass.
My wife is small, 5'03" and she didn't have any problems opening or closing the TM. Only problem was trying to left the hanging cabinet above the sink.
Can't comment on the height issue. I'm 5'06" and as I mentioned, wife is 5'03". Can actually jump up and down and not hit my head :P.
We both love the TM, had a wilderness prior to buying this unit and my knuckles are no longer sore from gripping the wheel. I highly recommend it for anyone thinking of buying a camper.
Good luck on your decision.
