take a look at this. http://www.tiregate.com/prod_info.shtml anyone seen one in person? openions on this as a spare tire carrier please. i do like the look of it. it doesent have provisions for extra gas but you can get it with a hi-lift mount. i want a big fuel cell anyways, i dont want to have to carry extra fuel. might be a bit hard getting a heavy 40 in tire off or on that hi up. but it has better visability with the tire at an angle then straight up. i saw the stinger type that folds down which makes it much easier then lifting a tire, but i dont really like the length of the stinger needed to get the tire to the ground. im not sure which directoin i want to go yet. i like the diy unit too. feed back please, thank you.
