Just one opinion.
I've always thought their beds were placed at the back of the bus for other reasons & egress does justify the doors' existence. But, just for under bed access? Seems like reaching under or installing interior drawers or lift-bed brackets would be more rational to both builder & user.
Are you planning to use this space for something specific? House batteries, fresh water tanks, personal effects,
snow chains, tools & spare parts...?
I've slept in many places, but, never with an exterior door under or against my bed. That's actually my kid's worst nightmare - Monsters Inc meets Hellraiser.
We've spent so much time & effort sealing the air & water out of our conversion, I contemplate cutting each new hole. If I were adding an exterior access door, which requires an air/water-tight seal, it would be mid-ship with stairs. Far away from my dry toasty bed.
Once Freddy's demo was completed, we evaluated the time/expense of the repairs & maintenance required to continue. Our priorities & imaginations naturally aligned.
Keep investigating, when the time comes, you'll know how to complete the task or at least know why why you choose to decline.
This seems to be a common progression as each pre-owner/planner evolves into becoming the sole-builder & financier of our dreams.
Just one opinion. You are clearly one of us.
