If you go with a standard height trailer you have the standard wind drag.. on a stacker you have much higher wing
drag,, he might give some thought on the front design of the trailer.. also consider the height based on the truck
height, 4500s are taller than a 3500.. a 5th wheel is more stable thats part of the reason semis
use them... I really look close to the frontal area of the trailer I build or buy... I pull this one with a 3500
2wd dually diesel 6 speed stick.. if I built a new one I would make the LQ much smaller and add a 3rd axle
