Many cities have ordinances restricting the type of vehicle and the length of time any vehicle may be parked in certain areas. For instance, my city has a 120 hour rule for any vehicle parked in the city, a 5-hour rule for big rigs, a 48-hour rule for trailers, and RVs, and other assorted restrictions - none of which are posted anywhere but are the law all the same.
You might consider checking the parking ordinances for where you live to see if your vehicle is a potential target for citation or towing.
