i have an 05 xb and i am wanting to mount my tank under my car by behind the rear tires. up close by the bumper. i was wondering what tank fits the best with the most air capacity. i was thinking of using a pancake style or a 5 gal slim tank but the 5 gallon seems to long to fit there. if you could post any pics as well it would be greatful. going to order my tank soon so that is why i am asking now so i can order the right tank

thanks
