I do not have a Leprechaun. I did just buy a Sunseeker. But thought I'd chime in for what its worth. Coachman had some features I liked. Floorplans seemed better overall. Beds were longer at 80 inches. More corner showers which are also bigger. But the biggest negative was the rubber roof. If Coachman had a fiberglass roof like the Sunseeker I probably would have bought one.
All previous rigs below are sold - waiting until the kids graduate to the buy the next one!
