We have a new 19. My boys are both 6'. I don't see any scenario where anyone over 10 years of age can sleep on the cot with the bulkhead cabinets there. There is very little height, maybe only 22" per bunk. My second son either sleeps in the truck bed which has a Leer cap or sets up the tent weather depending. In a pinch, one can sleep on the floor, lots of room with legs under the bed table.
We bought our last Escape, a 2007 17B as an upgrade from the 1977 Trillium 4500. The Trillium had bunks and the kids were around 10 years old. It worked great because the bulkhead cabinets were removed. We bought the 17B expecting to build bunks but it didn't work out.
Here is my link, I used fabric from a military cot and fabricated a steel frame. Nothing touches the fiberglass. This was only a trial, I abandon the idea of the bunks.
