I have a Grand Design Reflection 323BHS--bunk house model.
Their Reflection series is very popular, and can be towed with a properly equipped 3/4 ton diesel truck. My trailer weights 11K, and has a pin weight of 2K--actual weight.
While Grand Design is a new company, they're doing so many things right. Their dealers are often the better dealers in retail markets, and they don't deal but with one dealer in a town. They keep color combinations to one--and they don't offer many options to simplify their business. They're mainly building fifth wheels, and have just come out with a couple of travel trailers.
This company is going to be a major force in the fifth wheel and travel trailer industry.
