How do you get into a travel trailer bunk bed?

My parents just bought a Jayco travel trailer. Just looking at it, there doesn't seem to be a way onto the top bunk unless you use a stool. Can anyone help?? (I know this seems like a stupid question) :)How do you get into a travel trailer bunk bed?
There should be a place for your foot at the bottom on the side and you can climb right up. You better check it out before going camping as if this is not possible and you don't have a stool, you could be in a bit of trouble. You'd hate to ask for help each time you need to get into bed. Enjoy camping - it's a great way to see America.How do you get into a travel trailer bunk bed?
Climb up the side!
