If you want to be comfortable and not worry too much about your car's limits, avoid mountains, if and when moving from East Coast to West Coast. Try to avoid those Rockies... Although it may take more time and it's a longer drive, take I-10 West (from JAX) and hook up with I-5 in SoCal North....
Also, drive most of the time at night...
This may be water under the bridge since the original inquiry was placed here 2 years ago....

Is that a modern world Winnebago? ... and they don't stop for anybody..

Dark Helmet: Before you die there is something you should know about us, Lone Star.
Lone Starr: What?
Dark Helmet: I am your father's brother's nephew's cousin's former roommate.
Lone Starr: What's that make us?
Dark Helmet: Absolutely nothing! Which is what you are about to become.

That's a long way south. If the origin is in the US northeast and the final destination is the BC coast, the best mountain-avoiding route would be to cross the border in Manitoba and follow the yellowhead highway (#16 and #5), then take highway 1 at Kamloops. Still a bit longer than taking I-90 to Seattle, but the highest elevation on the whole trip is under 1200 m (4000 ft).

Finally I know driving details about the Northern route... thanks for your driving tips. I have driven many times from Los Angeles,Seattle and Vancouver to Okanagan through Kamloops, hauling kinds to hockey camps - but I have never been beyond Calgary/Edmonton (coming from West). Now I live in Deep South, right next to I-10, and I drive frequently Santa Monica/Jacksonville/JFK-New York several times a year...
