Having traveled / camped here in Ontario and many US states from east to west I'd say a good universal length that will get you on pretty well any site is no more than 25' coupler to bumper. This is especially useful when traveling, not reserving but instead just showing up. That said, I never had any site I couldn't fit on to with our previous Spree which measured 26' 9" coupler to bumper BUT there were a few times it was really tight - ergo, why 25' tops to me would be as long as I'd want to go. JMO. ;)
