Question on bracket spacing

[smlobx]

noob question...is there a standard spacing for the brackets that support most RTT's?

My trailer has brackets that are 60" OC....

I have no answer for you...

...the old drag racer in me read your thread title as "Questions about Bracket Racing" and went Ooooo! Lol!

Mine (ARB) are 48” I think, but adjustable on the other axis.
