My parents are talking about driving the AlCan (Alaska-Canada Highway) and down the west coast into California in their motor home.

I was wondering if anyone has any tips or suggestions for them to get the most fun for the least money...

Fun sights?

Good campgrounds?

Tips for keeping costs down?

We've driven it before, but in a small car...just getting where we needed to go...not really stopping to look around...

Would appreciate any help!
