Looks awesome man, congratulations. That’s a major milestone, worthy of celebrating.

You don’t need to completely weld the lapped seams completely, the factory never did. Just plug weld them together. As a general rule of thumb, I like to space plug welds no further than 1” apart. Hammer and dolly the pieces together as tight as you can first, then buzz them up.
You’ll have to reapply seam sealer to everything afterwards, so don’t stress if you can’t get them perfectly tight everywhere.
Looks great, keep up the good work!
