GFC V2 for 2014 through 2024 short box Chevrolet Silverado 1500 or GMC equivalent. This unit weighs about #275 has no effect on truck handling. No wind noise as the design is close fitting to the truck. It has only been used 1 night this past June. This unit has front and back windows. Back window is block able. The tent has all the windows as well. It has an additional sleeping set up to the standard GFC in the creation of a 10 inch by 56-inch section that allows the upstairs bed to have an additional 10 inches in width when in Bunk mode or 18 inches in gap space to get up and down at night, when used this way the sleeping space is 72 x 56. Custom panel, foam cushion and sheet were made for this set up. So you can sleep with 90 x 56 cushion set up or with 72 by 56 set up with gap to lower level. All the cushions have an additional 1/2 inch closed cell foam mat cut to fit from Thermarest. This is the type used in back packing. It softens the sleeping enough for me. One side of the mat is green used in warm weather and the other side is silver used in cold weather. Included with the sale is J Edgar drip rails, 1 Shittco awning blocks and rods, front molle panel in fiberglass from Gray man tactical ( not the bags you see attached to it, they were a gift to me). GFC lock covers for the side panels, magnetic lock covers for the back panel. Back panel has the privacy shade that I leave in the uncovered position when driving and then button up when you don't want anyone to see in the bed of the truck. This unit is in tip top shape and has always been in the garage when not driving down the road. The panels are black under the wrap. The wrap is easily removed vinyl. The interior insulation panels are just Velcro and can be removed as well. installation cost at GFC center in New Braunfels. located in central Texas.
