Wife & I "DID THAT TRIP" 5 or so years ago. As stated (I use diesel) much less in USA even with the terrible Xchange rates now. We are also on Van Isle.
We went Canada, return USA. If this is "The TRIP of a LIFETIME" forget the cost. I probably wrote all mine down, but I can't find, nore remember one way or the other which was cheaper.
ONE major thing 2 months is not enough for any amount of sightseeing.
We went thru BC, Al. SK. lets just say ALL provence's incl. NB,NS, AND PEI - back we crossed out of Prescott ON. then about across I80 in USA.
We were away about 80 days - and it was NOT enough, mined you we spent some time with family in 3 or 4 areas.
If I went again I would take at a MIN at least 90 days, as I recall
I drove about 1/2 the days we were away.
Whatever - have a good time .
I'll NEVER be an "EXPERT" (In math.X is an unknown factor and a "SPURT" is just a drip - under pressure)
