I can tow a billion pounds through the mountains without worrying about a thing . My parents drove across the country a few times in a 38 foot RV that had a front mounted well technically mid mounted 8 . 3 l Chevy V 8 and had no issues in the rocky mountains . But they told me their friends with a diesel pusher aka rear engine struggled in the high altitudes . Seems to me the turbo in the diesel should be able to make up for it unless boost is being measured relative to the ambient atmosphere , but apparently it wasn ' t the case . <| sep |> From what I read , you could easily and quickly make more financial hardships . <| sep |> I honestly would if I could , but I needed to be realistic , going from Oslo to Trondheim via Flam is a lot easier logistically with flights .
