Don't be packing all that food!
Surely traveling the DelMarVa area coast there will be several towns with at least a supermarket every day.
Buy what you need for the next day then. Saves on packing too much stuff.
Keep your load to a minimum. 200 miles in that area sound quite doable.
We've done 200 mile loops like that near the south rim of the Grand Canyon (a bit more challenging at 7500' than by the coast!) on our tandem. The max we packed was 22 lbs of gear. Stores/facilities are 50 or miles apart in that neck of the woods. However we do not pack a tent and stay in motels.
Most folks tend to overload their bike.
Enjoy the tour!
