Grand Design has outstanding customer service. Like all other RV companies, Grand Design uses the normal brand name components. The difference is Grand Designs willingness to work with the customer to make things right.
As for the 376, make sure your toys will fit through the smaller garage door. Also, I have heard headroom can be tight for the toys as well. Other than that, I love the 376 even though I have yet to see one in person :(.
