We have been very happy with our Grand Design Reflection 337RLS (does not have two doors into the bathroom, by the way). You will find other brands in the same price range that are built about the same but, as Dan said, Grand Design's customer service is head-and-shoulders above the rest. It's especially important for us, as full-timers, that we don't have to go back to our selling dealer for everything. Grand Design will work directly with us.
If you have the truck to pull them (at least a 1-ton dual rear wheel), the Solitude line from Grand Design is very nice, too. In fact, I would recommend at least a 1-ton single rear wheel for the Reflection 337RLS as the loaded pin weight is around 3,000 lbs.
Anyway, at 36' the 337 has been the perfect floor plan for us in our mobile lifestyle.
Feel free to PM me or ask specific questions if you like.
