Frame is 60" wide and will have 1/4" outside plywood lapped over it, so trailer will finish 60-1/2".

Here's the skinny. If I use a 72" hub face to hub face axle, I'll have 1-1/8" clearance between tire and trailer side. Debating on whether I should have the axle built 74" to give me 2-1/8" clearance.
3500# axle with 2000# leaf springs and shocks. What do you think?
