We are very happy with our Reflection 303RLS. As you said, it is perfect combination of layout, weight, and length. You can get to the bathroom and fridge with the slides in. We have had ours since Oct 2013, and have been 15K miles with only minimal problems -- not bad for #314 off the line in the first year of production in the first year of company business. We had a tech question and called Grand Design. Hearing our name, the tech guy asked if we were coming to the rally again this year. Can't say enough about the service and support.
I searched for nearly a year, trying to stay under 35', and ended up with a Grand Design Reflection 303. We've had it since late 2013 and have about 18000 miles on it. We're still very happy with the unit, the floor plan, and Grand Design customer support is outstanding.
We bought our Reflection 303 in Nov 2013 and have over 12000 towing miles. We are very happy with it. Although we've only had minor issues, Grand Design service and support is outstanding. Every other owner we've met is also pleased. Check out the owners forum.
