Hi Paul,An XLII will have ribs every 32" and the aluminum skinning is pretty strong..So, if your not on the ribs, you will still be ok. Stay safe!Nick-
The roof is structure on a Prevost at shops you see 2 or 3 people walking on one carrying a roof top
Hi Nick,Since the GMs are a similar aluminum skin design, do you know if that would be true for them as well?Thnx
