ADVICE FOR THE BEGINNER

hey guys i am stepping into step decking sometimes second part of april
im not new in the trucking industry , been car hauling since 2011.
i have several questions :
i have 1999 kw w900l with stretched 18" frame (it was stretched to fit 2 car head rack for the car hauler)
i won't be able to tell you exactly my frame length but after attaching step deck i have around 5' from the edge of the trailer to the sleeper (edge of the trailer signed up with 2nd axle) , fifth wheel can be moved only rearward (all the way to the front) . i brought my truck to mechanic today to have pm done and some minor repairs , he advised me to move 5th wheel with the plate foot closer toward sleeper for better weight distribution and more comfortable ride (otherwise he mentioned that my steer will be at 7-8k and i will always weight distribution issues).
trailer will be used 2015 doonan , aluminum step deck , triaxle (3rd axle is liftable) , 17.5 wheels
im looking at various videos and advices from friends on binders , chains , straps , tarps , ramps
can anyone advise new vs used , made in usa vs china , ramps
half of the guys referring to the place in granite city il for most of the equipment
will be glad to hear some feedback and advices
i currently driving stinger pete 388 and planning to remove headrack on that truck as well and have it ready soon .

 

edge of the trailer lined up with 2nd axle ....sorry autocorrection

 

id say king pin somewhere in the middle between drive axles ...

 

What's the best way to insert pics ?
I used to have Photobucket but I believe there is an issue with them

 

My trailer is triaxle
