The current issue of Trailer Life has a very nice article on the brand new VR1. For those of you who know Coleman Davis, formerly of Montana, the VR1 is his baby. It has sheet metal to include that A frame area of the travel trailer within the inside dimensions of the rig. In other words, this is a travel trailer that makes interior use of the area over the A frame. The resulting pointy nose also should help with wind resistance (i.e. fuel mileage) and may also help with stability in the wind, to some degree anyhow.
