Florida to Vancouver

[cahm]

Hi,

Any suggestions re best RV route to take from Largo Florida to Vancouver or even closest USA destination near Vancouver. We will leave Largo around the first week in Apr. and have no time limit. We will then travel back through the rockies on to Ottawa for family visit and back home to NL, Canada. We are 2 seniors in a 35 foot MH with car on dolly. We need to have an exact route. Years ago we ended up somehow going through NY. We want to avoid the busy highways.
I am working my way through the threads and found one possible route. We are also looking into getting the garmin gps for rv's.

Thanks
C
