Rolling around the flat lands is one thing, but once they hit the Rockies it's gonna have a hard time in a lot of areas. The 'yota will get damn hot through Colorado and Utah, and the fact it's 105ish won't help at all
Getting to the 5 from SLC, they'll have to take 80 through Reno and THAT drive sucks monkey balls. It'd be way better to venture through Vegas and onward to LA.
