Ok, I need to move a 240gal tank (8x2x2) in the next week or two. Its a used glass tank that I got for $175, filled about 4 inches from the top and it held the water, sat in the garage of a guy getting out of aquariums for about 3-4 years. I am using my 89 Toyota 4WD Pick up truck to move the sucker, its a long bed with a 7ft bed, and if I open the tail gate its over 8ft. Im only moving the tank about 4-5 miles and not taking any freeways so I was just going to strap the puppy down. I moved my 180gal in the truck about 15 miles, went on a freeway without any problems. So if I put the tailgate down there is enough room, but my concern is because its such an old truck the tailgate isnt perfectly level with the bed so this could add more stress to the tank, should I be concerned about his? The tailgate maybe about ½ and inch lower than the bed. I was thinking of putting a piece of ply wood on the tailgate to slightly lift up the area the tank would sit on and hopefully level it out better. Im hoping to avoid using a entire piece of plywood under the tank when I transport it form the guys place to my home. Any thoughts on this? Am I being overly concerned?
