Call the Colorado highway patrol, and the Utah Highway patrol (numbers are
on the web sites) and get a straight answer that you can rely on. Get a
name of the officer, or whomever, that you speak with.

You could drive it home without doing anything and the odds are you would
be fine, but on the other hand, if you get pulled over by an officer not
having a great day, you could end up paying to get your van out of the
yard after they impound it. If you get into a wreck and someone proves the
brakes weren't up to snuff on the unregistered van, it could get ugly for
you. Just saying "a guy on the VW list said..." ain't gonna help you <g>

You will find that its not gonna be hard to do, but do yourself a favor
and go about it the right way. Then you can enjoy your trip home and spend
time learning about the van, rather than worrying every time a patrol car
comes into sight.
