I based this off the heavy incinerator from the fallout games. Perfect for all your post-apocalyptic needs.
It's textured with Vray materials and I've included some custom texture images. I've also designed it to be turbo smoothed with a smoothing separator in case you need more. Also everything is UV mapped so you can easily apply your own textures if you want a different look.
Just put the textures in the working folder and you're good to go.
