Great post Homer. We did Ottawa to Disney/Key West 5 years ago and the Washington portion was definitely the most intimidating portion of the trip. First day we went to Hershey to meet up with people we rv travelling with. Looked at map and decided we either needed to get up really early or swing way west. Decided to get up at 2:00 and were on the road by 3:00 am and I have never seen that much traffic at 4:00 am in morning and I could not imagine going through with morning rush hour.
Our Route: I-81 to State Route 15, I-270 to I-95 which we took to Key West. Only done it once back and forth and do not have any other routes to compare it with and look forward to hearing about your success with your route.
Tip for Canadian Credit Cards at the Pumps in U.S.: use the 3 numbers of your postal code followed by two zeroes which will give you a 5 digit "zip code" that is linked to your credit card for security purposes. If you prepay with credit card, you will get charged double conversion fees which really add up.
The great news is that gas is under $1.50 per U.S. gallon as some of the central East Coast states.
Have a great trip.
