Ehhh...what exactly is wrong with rivets?
Mine was factory made in '88, riveted aluminum skin, tube steel frame. Still holding tight as hell, original paint still looks OK...couple of minor chips and scrapes, a couple loose rivets (easily fixed) down in the galvanized steel lower bay area but nothing anywhere that smells of manufacturing defect and it's held up VERY well. The only thing that actually dates it as older is...well, it's on a Ford F450 frame so it's got a giant pickup for a nose/cab
.
But the rivets have held up perfectly for...God, 17 years now and you'd never guess it was that old unless you knew Ford medium trucks real well.
GLUE!? What the hell?
