The FW I'm considering has a standard, solid, pin box and no shocks. If you could only choose 1, which would it be; shocks or pin box? Assuming I can get 12v power to the front vent, which fan do ...
I agree with filrupmark on the trailer setup order list.
Fans would be done immediately, too.
Remember shocks on a trailer -if speced properly will have great control on suspension rebound. Rebound is what starts the repetitive harmonic cycles that cause all kinds of ride/ handling issues.
