Take your van in, get the oil changed, the fluids topped off and such, check your tires. Make sure your spare is in good shape. I bet it would do just fine!
The only thing I worry a bit about is that it's something like a 3000 mile trip...now, that'd put it over 100K while we're on the trip, PLUS doesn't it seem like I'd need to have the oil changed on the other side, too?
But then...I suppose in a place like that, they likely have Jiffy Lube and stuff like that. Here, you have to make an appointment and drop your car off and it's a hassle. I forget that it likely isn't that way everywhere.
