I've had no problems getting around and finding parking in small towns and rural areas, at 30 feet, if I'm not towing, because I can often park by backing into an edge of lot space with the long rear overhang hanging over the edge. Towing takes away that option for me, I tow only when I have a longer term destination where I don't want to move the RV.
Getting through Houston, Dallas, OKC, Austin, San Antonio, KC, St Louis, has not been a problem. You are not that much bigger than a delivery truck, and big over the road rigs go through cities all the time. You can even use major city streets if you know which ones the trucks use.
The problem in big cities, and crowded suburbs, is finding parking, because in those places the parking lots at shopping centers, supermarkets, strip malls, even fast food places, tend to be full, and you won't always find the extra space you need, nor room to maneuver.
There is a similar problem in residential areas, even where street parking is permitted. I have managed to find parking at friends homes in Sugarland and Katy, they'll park a couple cars at the curb when they know I'm coming, and move them when I get there so I have a big enough space to parallel park into. But I wouldn't try that in more congested neighborhoods like Rice Village, or the Museum District, or anywhere around the Medical Center where it is difficult to find a place to park a car except in a ramp.
