There is mainly just three roads that go up and down the East Coast I95, Route 301, US17...
Your trailer probably is on the two big side to go up and down US17 and US301 as they go through all of the small towns...
Fuel stations is another problem for big rigs. Kinda have to always fuel up when on I95... What most folks do is fuel up before hooking up again for travel...
The other problem is the big cities like Myrtle Beach and Charleston SC etc are not on the I95 corridor and you have to go 60-70 miles to get from I95 to the towns on the coast...
The south part of Myrtle Beach has great camp grounds but here again you are a little on the big side so that will rule out a few good ones...
Some times going big is not all that good haha...
I can still do a McDonald drive thru with my off-grid setup....
