I sent you a PM.
You should change your registry if you have not got the 30' any more.
My Clipper has the fiberglass roof and I assume your XC360 has the same.
There is no problem walking on the roof (approx 200lbs) as long as there has been no water damage to the underlying ply of luan (plywood).
If there has been water damage, the roof will be soft in spots. The glue on the ply to f/g will have parted and give no support. If you have a soft spot I would use some other support to walk in that area, as a direct footstep may crack the fiberglass and also could do some damage pushing down the insulation and the interior ceiling.
The problem areas may be near the skylights or vents.
You must keep a close eye on your roof to avoid costly damage that will show up after the damage is done. Preventive maintenance is always the only way to go.
Hope this helps.
