It sounds like "Disappearance" to me. I have seen it a couple of times. Here is a link that will tell you about it and see if it is the movie you are looking for:

Probably the hills have eyes. let me tell you about the plot, maybe it has something to do with the one you are talking about;

a family( consisting of father,2 daughters, a son, a baby, the husband of one of the girls, a mother, a dog) take a trip to the desert where the government conducted nuclear tests(they didnt know this) THEY DO DRIVE A SUV! then these "cratures" are actually humans who are affected by the nuclear tests. they attack the family,and eat the bodies. everybody except the dad and the eldest sister. but to make it short, at the end the husband, the baby, and tae girl are teh only survivors.. only to be that the film ends with a pair of binoculars looking at the survivors.

sound familiar? hehe well go to this website to find teh actual plot:

The Hills Have Eyes

It sort of sounds like The Hills Have Eyes...not sure if they are in a white SUV. Hope this helps.

There's a lot of movies like that. The only one I know is 'Pumpkin Head' or 'The Hills have Eyes'. I'm guessing it's a horror movie. Sorry, more description would help. :/

Bigfoot

Jurassic Park?

Sounds like the hills have eyes dude.

Oh, and the dog gets half eaten in the beginning?

It was on sky movies the other day, can't remember the name,

2 secs.

Is it out in the desert and is Cheech (from Cheech and Chong) in it and in the middle of the movie, do about half the people turn into vampires?... I can't remember it either... have a beer
