Travel trailer for taller person

Look at brands with an arched ceiling. We have that and it makes the interior seem a lot bigger. I'm under 6' so doesn't help for that. I don't think I've ever seen a TT with the shower not against the exterior wall but haven't paid attention to that. While an arched ceiling will help a bit, the ceiling height gets back to standard at the exterior wall due to the tapered trusses.

If you're not a senior citizen yet, wait until you are and you may have lost a couple of inches or more. Problem solved, lol... :)

I am 6'4" tall and have same problem. I seldom use RV shower though as we typically do not have water/waste hookup at the type of campgrounds we prefer. I just suffer. :)

However, there are some lines with taller ceilings. Check out Jayco JayFlight with 81" of interior height.

Rockwood, Nash, Arctic Fox, Outdoors RV.
The Rockwood head room is 6'6".
Use the outdoor shower if you don't fit.

Good luck. I am 6'1" and have never found one that I could stand upright in the shower anywhere except directly under the skylight. Even there, I had no excess room above me.
