Our 25.2 has no rear ladder, and neither did our previous coach. I have the same ladder, and I kept it in the rear compartment of our 25.2 for a year or so. Then I needed that space for something else, so I keep it in the pass through between the front cabinets. Those ladders aren't cheap, I prefer it inside.
It's been awhile since that pass through storage on Vegas/Axis has been mentioned. It is surprising how many folks don't know it is there. It is a great place for a broom, a fishing pole or anything long.
Bad decisions make great stories!
