On the road it won't matter how long you are, your space is your space.
Width is the same and that's where an over-the-road problem would matter.
It will be a lot easier to use pull thru sites. Most of those CG access roads are wide enough to accommodate large rigs to access a pull thru. At times, trying to get to get to some back-in sites, the access road to them was the problem...too narrow and tight to turn.
On any trip , I always plan ahead and do a visual of my intended route on Google maps . I use the satellite function to actually see the landscape.
Makes it easy to pick n choose large easy in/out fuel stops as well possible tight turn options.
Often a website (youtube has many) will show a video of each site at various CG's. Having a visual of a site prior to occupying it can sometimes be helpful.
Tight turns in towns will require you to use more of the other lane to to turn right. At times, I sometimes needed (it was easier) to go around the block to turn at an intersection with no other traffic allowing me to use ALL the lanes, or drive past my intended right turn, then make a u-turn in a large parking lot then come back and make a left. A lot easier to make lefts towing long trailers. :)
