A question for all you experts...We are planning a trip to Alaska soon. We have a '99 Southwind with a Ford V-10. Coach has about 75,000 miles on it but has been well maintained and runs well. It has original belts and hoses. Should these all be changed before we leave or should I leave things as they are. I carry a new belt but not any hoses. Needless to say, we will probably do 6-7 thousand miles on this venture. I realize that common sense says, "change 'em" but ... What are your thoughts?
