Our fiver is 40' and have yet to have an issue getting a sight. We always call ahead to ensure they have a spot big enough for us. Biggest issue we have had is navigaging through some parks andlow tree branches. If we come across a low branch we just talk with the park manager or ranger and either they have trimmed it for us or let us trim it ourselves, we carry a pole saw with us. One thing I've noticed is when I say I have a 40' fiver they think it will fit in a 30' site and end up going back to the office getting another site. Enjoy your travels and always remember to look up.
