Re shaping Tote N stor tank

[High Ball]

Bought a used Tote N stor tank as we will be going to a park where there is no sewer connection for a month or two. Looked for a place to store the tank and in front of engine on back corner the tank fits almost perfectly. I can add a large hook to grab handle and rachet strap it in center so I could keep it indefinatly as it would not be in storage bays. The problem is that when I close the grill the chock mount and the tubular bar catches the tank. It is just enough so it doesn't quite fit I have only about 1 inch for the grill to close. Wondering if I heat up the top side of the tank with a heat gun and pushing on the area if plastic would push towards the inside and stay molded that way. Any of you tried to reshape plastic this way without putting a hole in it ?????
Any info would be greatly appreciated.

you can definitely reshape it, the key would be to heat the area around the point that you want to move inward, that way the plastic stretches without getting a hole in it - use a sharpie and mark the section, then I would use a round object to gently press down as you increase heat until it shapes easily. Go slow
