Hi. I'm writing a script:

Mark and Dan get into the back of the RV. Phil shows them around.

Next scene (ten minutes later)

Phil's driving. Mark and Dan come up to him. / Mark and Dan join him in/at the front of the RV.

Hi. How would you write the bold-face sentence? Does one of my suggestions work? Thanks.


To come up to someone is to approach him and stop close to him commanding his attention, not to come to the front of a thing where he is. So, although they are indeed approaching him, that is not what you mean. You want "Mark and Dan join him at the front of the RV."
