You will need to take 695 around Baltimore as propane is not allowed in the Baltimore tunnels on both 95 and 895. Avoid DC at rush hour!!!!! Nice overnight campground in Jacksonville fl just off of 95 is pecan park rv resort
. We stayed there on our way to Disney last year. I have seen many post about Carolina crossroads
for an over nighter in NC.
Check your tires for heat at every stop. Check your tire pressure before leaving home. Being a newer tt, check your lug torque before leaving. At every stop double check your hitch and trailer pigtail to make sure nobody monkeyed with it. Take it slow and easy. When we went to Disney we did 9-10 hrs first day and 3 hrs the second day going down. Coming home we did the whole thing in one shot, never again. 8-9 hours is a good expectation. We didn't make reservations but took the exit now book with us. When we felt stopping would be a good idea, we pulled the book out and found a campground. We called ahead to verify availability. This worked well.
