you sound like my son..... you have two..... LOL :D
I sold my trailer some years back. I have a relaxing hour to the strip. Make it down there about 6x a year...… That's a lot of car and money for 6x a year... LOL. That's why I'm planning on a low dollar, highway geared, very streetable 12.7's.
I would guess 135 bucks to ship that rear end... but that is just a shot in the dark guess. :D
