X2 on having a pic.
Had the same problem with my Lacrosse.
I would first make sure my slide out is adjusted properly, mine was not.
Matter of fact none of my 3 slide came from the factory properly adjusted.
(that's a story itself
After slide was adjusted right, having the crushed molding changed on the unit itself. It still was hitting to hard imo.
So I cut / trimmed the wheel skirt with snips so it would not hitting anything when closed. You cant even tell I cut it to look at it. Simple task that my deal just couldn't do.
