Hi Len....first, when you reply,use the "reply to this post" link at the bottom of the thread. This just keeps the whole topic in one thread and gives continuity to the topic.
Now, roads are usually very good, with the worst being in northern Ontario. Keep in mind these roads are being up graded all the time, so some construction may not be avoidable. There are dozens of both private and provincial parks along the way.I suggest you go on-line and hit each Provincial Tourism link. They provide info on every aspect of travel, accomidation, etc through their provinces. I have driven across our country twice, and if possible take enough time to see the high points in each province. Sounds like your in for a good trip, enjoy, and Please contact me if I can help out further....Brad

P.S. In my opinion, you have joined a super RV web site. Any questions you have, don't hesitate to ask...
