Low Tide moving is ussually researved for smaller tanks. What your thinking of doing will put a lot of stress on the tank and your friends. I have moved a 33g this way but ALL the rock was removed and as much water as possible then when I got it to the vehicle I added water just to cover the sand. No way would I attempt this with even a 75g. And I would be surprised if what you want to do is less than 700lbs. A couple of rubbermaids....less than $30, a wiped out back is forever. A shattered tank.........just not worth the risk.
