We take I-69 from northern IN thru Indianapolis, Louisville, Nashville, Birmingham AL, Montgomery, AL on I-65. Then catch US231 down to I-10 thru Dothan, AL. From there we go along the west side of FL via US19 (4-lane). You can then catch US98 over to I-75 then south.
You can go through Sarnia/Port Huron and stay on I-69 following the route above. Indianapolis is no problem with I-465. There is some construction through Louisville at the Ohio River. Working on a new bridge. Nashville traffic has never been a problem for us pulling our 5th wheel. There's often construction along nearly every route, but timing is always the trick.
We've taken this route several times. It would be shorter for us to take US23 south to I-75 in OH but I hate going through Cinci. You run the risk of traffic backups no matter how you go but I-69, I-65 and US231 have worked well for us.
