If you zoom in on that hitch to 500% it looks more like a trunk to me? The square stock looks a little thin as well. If it's a gas tank, I want to know how he sealed it. for sure. IDK, my Impala had a trunk and the tank was in the rear like all my vans, so. Looong ass U bolts.

I'd feel much more confident if he'd fix that, upgrade the hardware to U bolts and put some 1/4 inch plates inside and out.

I did run over my Baby Sister in Law's Tricycle with my 65 Chevy Impala. Tammy was crying because I backed up over her bike, I was crying because the axle punctured the tank and I had just put 5 bucks in. Found one and pulled it at the junkyard. In town! Tammy got new bike for Christmas.

Shure wish I would have know about that trailer hitch bolted through trick though.
I wouldn't have had to take the trunk lid off every time I hauled my dirt bike. grin
