You most likely will travel through the Fraser Canyon from Hope BC to 100 Mile House.
An easy trip without any road problems and great scenery.
Done it many times. No Walmarts between Hope and 100 Mile House.
But there are many opportunities to pull over for the night.
Once in 100 Mile there is free parking at Save On Foods on the north end of town.
Near Hope we stayed at the shopping mall in Chilliwack.
From there it's an easy day drive to 100 Mile House.
From 100 Mile to Gustafson Lake you will be following a gravel road.
