i can buy a 6x12 single axle,ramp door,side door v-nose for 2300.00 brand new.never seen a 8x12.you measure the box,not the tongue and fenders.just the square part of the box without the v-nose.
8X12 is a fairly common size - although it's usually shown as 8.5X12... Here's just one place near me where I've bought three trailers from over the years.. Scroll down for the 8' series..
