My wife and I had a very nice Forest River Blue Ridge for several years, but unfortunately, several minor inconveniences and shortcomings caused us to look for a replacement. A Grand Design Reflection was on our short list when we bought the Blue Ridge, and my wife was immediately drawn to the Solitude this time around. Our only real limitation was overall length due to the available parking area on our property, and the 310GK-R was ideal in that regard.
We are completely satisfied with the Solitude's quality and design. We ordered the unit with a queen bed and did not desire a washer/dryer or dishwasher, as we are not full-timers. Therefore, we have an abundance of storage in the living areas, especially with the addition of some strategically-placed shelving in the bedroom closet area. We had no need for the outside pull-out kitchen or generator, so there is space underneath for everything we typically carry.
Over the 14-or-so months since delivery, we experienced only two problems of note. The first was a defective temperature control on our Furrion oven, where the selected temp would not match either the displayed temp or the actual interior temp. GD replaced the oven.
Second, a compressor controller in the living area air conditioner failed. This was easily resolved via the Coleman AC warranty.
The Solitude is equipped with desirable features we never had before, like a built-in vacuum cleaner system, a second awning on the living-side slide-out, a retractable TV in the living area, very comfortable reclining/heated/massaging/lighted theatre seating, a full-size pantry and one-key access to all exterior door locks. The interior cabinetry is very attactive, and the lighting is intelligently placed throughout. Perhaps the major selling feature for my wife is the abundance of windows, which gives the camper a very roomy open, airy feel.
At this point we are extremely pleased with our Solitude and we expect it will serve us well for years to come.
