When special ordering mine in 2007, I made a bold decision (bold to me anyway) to request the factory "Not" mount the roof rack or ladder, but instead place them inside the RV. I disassembled and stored them in my basement. So far I have not regretted that decision. The only time I get up top is to wash the roof of which I use my home ladder for that.
I do admit I was initially inspired to leave them off to improve my walk-around clearence of the RV when parked inside my garage. If I had the ladder attached, I'd have to open the garage door to get around the rig. But I quickly appreciated the cleaner appearence, ease of washing, and less caulked-over holes in sensitive places.....ie the roof.
The only concern I have is when camping, if I tangle a branch in the a/c or other vent. I don't have any way of getting up there to untangle it. But given the PC is lower than most motor homes, the scenario is unlikely. So far so good.
