45 backing a 53' spread axle racing trailer

Backing a spread axle racing trailer say at a truck stop, any tips here vs a rwgular tandem trailer? Like would u set up differantly for a spread axle?. Sry if this seems likenew drier question its cuz im a new driver and schools dont have spreadaxle trailers

 

I believe its 8' spreads ill have to confirm but that sounds right.. Measured the bridge length from center of the kingpin to middle of the rear axle is around 46' which pjts the rear axle very close the the back. Which makes turning on tight streets tough.

 

attempting to add pic of trailer... check attatchment

 

how do i dump the back axle? there is a a releas valve for the air tank are you saying just yank that till its empty?
since we bought the tracter seperate there isnt any control in the tractor other than the tractor susupension dump.

is there a way to manual do it or do i need to rig something like a switch in the tracter?

 

There Are lots of outlets used For powering generater. It looks like there was a switch for suspension to move body of the trailer up and down. Not sure if this is the same thing as dump valvle i imagine that would move both axles up or down to level the elevator for the car. Anyway that switch is missing its just a hole now( maybe previous owner had it wired through there not sure. Have a race leaving friday from cali to connecticut wish me luck. When i get back ill run trailer and tractor to a trailer plave mayne i can get them to wire that dump val e. Ill have to wing it tilp then, and hope i have the room to make those tight right turns( it turns like a battleship) and that fromt axle is more like sliding than turning i worry a hit about popping the tire right off the rim .

 

I wonder if dumping tracor suspension would would pull front of the trailer down enoigh to put more pressure on forward axlento force it to pivot on front axle... Or would that just be a bad idea risking seperation
