I had a Sierra. The thing had problems and the dealer was******and the factory wouldn't even consider doing anything. The roof had started to leak and water was coming down through a light fixture at the back of the unit It wasn't long after this that I got rid of the Sierra and went to an Open Range. Both rigs were the same length and the OR is about 2000# lighter just from the slide mechanics. I am in my 5th year with the OR and wouldn't think twice about getting another. We did have a problem but the factory corrected it with gracious quality service.
Good Luck in your choice and Happy Camping.
