Passport 5260RL Ultra Lite Roof?

[JP4]

I just installed a vent cover on my 2012 Passport 5260RL Ultra Lite. I was told that you can walk on this roof, but as soon as I got up there I started hearing "crunching" sounds and decided just to scoot across the roof carefully on my backside (LOL). What gives, besides the roof? Thoughts?

Well some depends on your weight. I walk on the roof of my Copper Canyon, but slow and carefully.
Most 5er roof are 3/8 wafer board on light weight trusses 16' to 24' apart. Try to keep your feet over the trusses. I weight 190, go slow, and get a little give.
