Yeah, I've got solid shank rivets in places on the truck. And I've got a few pop rivets. And if it came down to strength, I could use huck blind bolts. They're like a high strength pop rivet. They're used under extreme shear loads on aircraft. And yes, I agree, much easier to hide than welds. Especially if you dimple the skins on the truck first (instead of countersinking, on account that the skin is so thin). Yeah, I hope it's a good welder, especially since it's been rebuilt from the dealership. I know that millers are usually used for industrial stuff. I'll get the numbers off of it to find out more about it.
