Has anyone welded the top seam or is that overkill?
I’ve wondered about that. Same with the side mount brackets for the axle.I welded all around mine to keep water out. You could use auto body seam sealer, but it won't last forever.
One thing is guaranteed. Unless your welds are 100% air tight moisture WILL find a way in, weld so the lowest areas have a way for water to weep out.I welded all around mine to keep water out. You could use auto body seam sealer, but it won't last forever.
