I don’t have a 19bh but I have a white hawk 24mbh and installed this bunk ladder https://www.amazon.com/gp/aw/d/B00HE...rv+bunk+ladder. I had to modify it by cutting the legs to make it a little shorter. It comes with nice mounting hardware and it is very light so it’s easliy removable if you need more space to access the lower bunk.
