Got a 2015 Momentum 385th 2 weeks ago and after first trip, very happy with the dealer and the rig. The B&W Companion Turnball Hitch is everything folks claimed and very easy to use.
I am new to all of this, but spent the last 8 years in a tent at my favorite Bluegrass Festival at Starvy Creek going in and out of tons of RV's and asking lots of questions. Really impressed with the fit and finish of the Grand Design products and believe it or not, use the Toy Hauler section with the bench seats for a picking parlor of sorts during rainy or inclement weather.
Myself and two of my friends all write Bluegrass and Country music and will use the 385th to go to festivals and talk to bands about playing our songs and jamming with everyone. The 385th was solid as a rock on the road and after getting the airlift adjusted and on the highway you hardly know it is back there. Of course getting used to NOT pulling into McDonalds or 90% of the gas stations out there is a quick lesson to learn. The dealer this week is going to swap out the B&W Companion to the B&W Companion Slider for my 6.5' bed so I can get a little more turning radius. Great products and highly recommended to take a look.
