Rear bedroom/closet slide out converted to bunk beds?

Has anyone done a mod like this? I would like a new Class A with bunks, but the $90k price is hard to swallow!

Looking at some older A`s for half the price, I`m looking at the ones with a rear bedroom slide on the pasenger side. I`m thinking the ones that have the full closet next to the bed could make a good spot for bunks like the newer ones have. I`m not worried about the work required to do it. looking for feedback on how it went and if anyone has any pics of before and after.

Thanks!
