The color of the interior wood trim is cherry stain, darker and more red/brown than the standard oak. The countertop is about 3/8 inch thick solid surface material (corian or corian-like) and it is the color of wet sand. The fabric is a mix of browns, tans and black. The floor is linoleum with a mid-tan color, and the carpet is a light tan. It also has an upgraded kitchen faucet with a pull out sprayer, similar to what you would use for a standard home.
I pull the 3912 with a 2008 Ford F-350, Powerstroke 6.4 liter diesel, single rear wheel. Pulls good, tracks good, stops good, but I won't be breaking the speed limit anytime soon.
