Yikes, that's pretty messed up.

I guess you could try to whack it gently with a rubber mallet or something, in case it came out of alignment. Maybe shoot some compressed air, in case some crud is trapped underneath that is blocking it shut. WD-40 maybe? I wouldn't jink with it too much though, since it should be a warrranty replacement, and if you mess it up any further the dealer might just refuse to cover it under the warranty. Do you have AAA with RV/Motorcycle? If not, I'd highly recommend it (some people have the AMA coverage with towing, and I've heard good things about them too). You get four tows a year, IIRC, so it's probably worth it to use one.
