It complicates things, limiting some choices of where to go, what site to use, but so does any increase in the size and complexity of your travelling rig.
Most of the places I go, public campgrounds on reservoirs, have few pull-throughs and limited extra parking at the campsite, but have extra parking space for trailers because so many people are bringing boats. But even those spaces are back-in, and sometimes tight, so if you wanted to use the car, you would have to take it off the trailer before storing the trailer.
Sometimes the extra parking is at the boat ramp, rather than in the CG, and there is a ramp fee to park there even if not launching.
