When you say you want to go to the same places you went to in your car that raised my eyebrows a bit. My 30ft. had a fair overhang in the back and it dragged pretty easy going into certain roads and areas. If you have no experience driving a larger vehicle it can get interesting real quick. I have found no issues with parking, their limits are so one vehicle doesn't take two spots, like some do at truck stops which annoys the truckers.
I suggest renting what size you are interested in and try it out for a weekend or so.
