Just remember the border crossing in the I-5 corridor are a nightmare at best. Osoyoos is way laid back in comparison.
# 1 highway out of Vancouver is a very busy highway thru Hope and north. mostly truckers in a hurry.
97 is a bit hilly, but should not present a problem, simply take your time and stay right, let the traffic go by if needed.
If for some reason you must use the I-5 corridor get off at the meridian exit in Bellingham go north and cross at Sumas, this cuts off much of the #1 traffic, and is an easier crossing than the I-5 or the truck crossing in Lynden.
we do this twice or three times a month. Sumas has RV lanes, watch for them and get in the proper lane early. they are way left gates.
