How are the roads through Canada and Alaska? Has anyone travled them recently? I have friends who recommend buying old and small trailers for this trip because the roads are so bad and will beat M/H and fifth wheels apart. Will be retiring in one more year and plan on making this trip from Alabama. Have a 28ft 5th wheel with slide and a 3500 dually. Plan on buying a M/H before retiring but, wondering if I should make the trip before purchase. Thanks for any info.
