Gas tank leaking

Hi y'all I got a 99 national dolphin 5350 with a leaking gas tank from bottoming out in driveways. I'm doing my best to get any and all unnecessary weight out of here but it's a process due to me being disabled. It's being a serious pain in the tush because it's right there at the butt joint of the underbelly and the back panel! We've put 5 patch kits on the tank so far, which works until it gets scrapped off(which usually is within 24 hours of spending almost $300 to fill it. I sure would appreciate y'alls thoughts on WWYD, tips, repair suggestions, or whether I should just replace the whole tank. I need the quickest, cheapest, most PERMANENT way to fix it. Thanks for taking the time to read my post, I look forward to hearing everyone's input! Have a blessed day!

Two options I can think of are; rear casters which keep the rear from dragging.
The second option is to have a shop make a skid plate for the gas tank so it won't scrape the pavement

I agree with Tony, perhaps bolting a steel crosspiece or along the frame rails would help shield it.

You might also check ride height, perhaps your springs are weak or broken allowing the low clearance. I doubt if this has been a problem for 19 years, I suspect something has changed. You might also lay plywood or blocks in the driveway to try and prevent bottoming out when going in and out the driveway.

A little history on the rig. We bought it 3 yrs ago. Unfortunately, it has a lisp on the passenger side and after doing a little digging I found out the previous owner broke the tag axle. Like completely severed it, It has insane welding marks! That is the side that keeps scraping

Maybe either replace the rear springs or add a couple of leafs.
