edt.....my trailer is a 17' flatbed, 7000LB. trailer. Sorry, dont have a way of putting pics on here. Tank is mounted directly in front of the bed rails, front end of the trailer. This mounting location doesnt take away from bed usage. Makes for a heavy tongue when its all filled up tho! Get a tank with bolt holes mounted on each four corners, weld 2 x 2 angle iron to the frame, and bolt tank to angle iron. Is really a sweet setup. Heavy tongue is worth the hassle of going to refill portable 5 gal cans all the time. Have driven trailer, with full fuel tank, a grizzley 660 Quad with 28" outlaw tires, my rotor tiller, my tractor and loader attached and my landscape rake attached to tractor about 500 miles this way, and no ill effects as far as handling goes. (picture the loading from front to back, quad was turned sideways). Drove it this way and to this location to donate some time to an atv park in southeastern iowa. (always looking for more seat time for both quad and tractor!)
