Offroad wheelchair for Keith

My name is Keith Russell and I am 24 years old living a very active lifestyle with a spinal cord injury. I am attempting to get a tankchair. What a tankchair is, is an offroad wheelchair made to go anywhere. Snow, mud, trails and anything else thrown at this beast is handled with ease. Where my current wheelchair gets stuck or it simply wouldn't begin to go; this chair will with ease. I enjoy hunting, fishing, hiking and have recently tried getting into competitive pistol shooting. Basically each of my hobbies is currently out of reach if it has rained recently or I'm limited to hunting/hiking on the edge of civilization. I'm not the type to sit back and watch but my current wheelchair is often making that the case. So can you help me get offroad mobility?
