I may ask him for advice because if he just plans on bolting through the floor I can do that but is that really secure enough? And would I bolt right through the supports or right next to them with some big ol washers? I have the next 3 days off and one way or another I'd like to get this bad boy mounted I just need to get some holes covered somehow
I would Absolutely *NOT*, under any circumstances, weld brackets to the frame rails. Drill holes in the "sides" and you should be fine. Do *NOT* make holes in the "tops" and "Bottoms" of the frame rails (The flanges).
Highly paid and well funded engineers worked this out for you already, just use some recycled round fuel tank brackets and bolt 'em to the sides of the frame and you're good to go.
