Gddim8 : In early Dec, we hauled our C34 from Windsor Ontario, to Bradenton Florida & returned home on the afternoon of New Years eve.
Although you're quite a bit east of us...& our route was totally along the I-75...you may find our method of breaking up the trip useful.
Our first consideration, was that we wanted to travel (as much as possible) during daylight hours...and secondly, as we have mountains to deal with in Kentucky & Tennessee, our first planned stop was to overnight in a Walmart parking lot in Georgetown Kentucky.
It took us about 9hrs to reach this first stop.
The Walmart lot was apparently a popular stop, as we had other RV's beside us when heading southbound & northbound...and I suspect that this is likely because it lies just at the foot of the Kentucky mountains.
Our #2 stop is actually the reason why I'm responding to this thread, because somewhere along your route, you'll be travelling on the I-75 just as we did.
Our second stop is the Fair Harbor RV Park in Perry Georgia Georgia RV Parks - Ga Campgrounds - Ga RV Camping - Pull Thrus WiFi Cable TV
Fair Harbor is south of all the mountains...& the big cities of Atlanta & Macon (both of which we're glad to get past..) and close enough to the Florida border, that our Bradenton destination (& in your case Naples) is within a day's drive.
We find that by splitting the long drive up into three manageable "day hops" & planning meals in advance (I'd be remiss if I didn't thank Popeye's chicken..) a challenging drive becomes manageable & something we're no longer overly concerned about.
Oh, just one more thing...always keep in mind that "Attitude is the difference between an ordeal & an adventure
