Mine is not a dually but it may as well be in the parking lot where I work. It was designed for very small cars and us psd drivers have a hard time. Then people park on the end where there is no spot so I have to cut and back and cut again to make each turn, if it was a dually someone would be missing a few body parts by now. One of these days I am gonna run over someones little ricer just for parking where there is no spot and I am getting tired of it. Think if I run over 1 or 2 the rest will get the point??? You guys would have no hope in this parking lot.
