Yes, the only difference between the Rockwood Roo and Shamrock is cosmetic. We have a 23ws Shamrock. We are very pleased with it. We have had one tent end come out of the channel on the door. Was reattached easily with silicone but am keeping an eye on it. There is a thread here with others having the same issue. We have not had any other issues though ours is new, we have been out on 5 outings to date with it, have not had any leaks. Though I don't like the blue light in the fridge, can't see worth a dang inside it. I would have the dealer change that out for a white light.
The trick to closing the tent ends is to turn on the fans, close the windows and door and the fan sucks the tenting in making closing up easy. Good luck on your camper hunt.
