I have a 2019 381th and a 2017 Ultra. Even though I full time I don't travel every week or every month, but have traveled quite a bit. I have not noticed any height issue, but then again I only load/unload when hooked up to the truck. Never hit when going in/out or off the ramp door. Never tried while disconnected but I can see where it may have an issue.
