An alignment method and system for connecting a tractor to a steerable trailer includes a connection roller which facilitates the connection by accommodating a variance in fifth wheel to kingpin alignment. The method and system also includes an alignment guide which visually assists the tractor driver in properly aligning the tractor to the interface member of the trailer.

1. A method for aligning a tractor with a steerable trailer, comprising: (a) providing a tractor having a central axis and a fifth wheel having a slot;(b) providing a steerable trailer, said steerable trailer having a trailer alignment system including; an interface member having a bottom surface and an alignment axis, said interface member rotatably connected to said streerable trailer;a kingpin disposed on said bottom surface and on said alignment axis of said interface member;an alignment guide disposed on said interface member, said alignment guide oriented perpendicular to said alignment axis of said interface member,said alignment guide having a first end which outwardly projects from said interface member, and an opposite second end which outwardly projects in an opposite direction from said interface member;(c) using said first and second ends of said alignment guide as a guide, backing up said tractor toward said interface member so that said central axis of said tractor is aligned with said alignment axis of said interface member; and,(d) continuing to back up said tractor until said kingpin is received and locked in place in said slot of said fifth wheel. 2. The method of claim 1, further including: in step (b), said first and second ends of said alignment guide being selectively extendable; and,prior to step (c), extending said first and second ends of said alignment guide. 3. The method of claim 1, further including: in step (a), said tractor having a first side view mirror and an opposite second side view mirror;in step (b), said first end of said alignment guide having a first planar member having a first edge, said first planar member being oriented parallel to said alignment axis of said interface member, and said second end of said alignment guide having a second planar member having a second edge, said second planar member being oriented parallel to said alignment axis of said interface member; and,in step (c), positioning said tractor so that a straight on image of said first edge appears in said first side view mirror, and a straight on image of said second edge appears in said second side view mirror. 4. The method of claim 1, further including: in step (b), a connection roller disposed on said bottom surface and on said alignment axis of said interface member, said connection roller spaced apart from said kingpin, said connection roller shaped and dimensioned to rollably engage said fifth wheel; and,in step (d), said connection roller rollably engaging said fifth wheel and guiding said kingpin into said slot of said fifth wheel. 5. A trailer alignment system for a steerable trailer which is towed by a tractor, the tractor having a fifth wheel having a slot, the trailer alignment system comprising: an interface member having a bottom surface and an alignment axis, said interface member rotatably connected to the streerable trailer;a kingpin disposed on said bottom surface and on said alignment axis of said interface member;a connection roller disposed on said bottom surface and on said alignment axis, said connection roller spaced apart from said kingpin, said connection roller shaped and dimensioned to rollably engage said fifth wheel; and,when the tractor is backed up to connect to the steerable trailer, said connection roller rollably engages the fifth wheel and guides said kingpin into the slot of the fifth wheel. 6. The alignment system according to claim 5, further including; an alignment guide disposed on said interface member, said alignment guide oriented perpendicular to said alignment axis of said interface member, and,said alignment guide having a first end which outwardly projects from said interface member, and an opposite second end which outwardly projects in an opposite direction from said interface member. 7. The alignment system according to claim 6, further including: said first and second ends of said alignment guide being selectively extendable. 8. The alignment system according to claim 6, further including: said first end of said alignment guide having a first planar member having a first edge, said first planar member being oriented parallel to said alignment axis of said interface member; and,said second end of said alignment guide having a second planar member having a second edge, said second planar member being oriented parallel to said alignment axis of said interface member. 9. The alignment system according to claim 6, further including; an alignment guide disposed on said interface member, said alignment guide oriented perpendicular to said alignment axis of said interface member,said alignment guide having a first end which outwardly projects from said interface member, and an opposite second end which outwardly projects in an opposite direction from said interface member;said first and second ends of said alignment guide being selectively extendable;said first end of said alignment guide having a first planar member having a first edge, said first planar member being oriented parallel to said alignment axis of said interface member; and,said second end of said alignment guide having a second planar member having a second edge, said second planar member being oriented parallel to said alignment axis of said interface member. 10. A trailer alignment system for aligning a tractor with a steerable trailer, the trailer alignment system comprising: a tractor having a central axis and a fifth wheel having a slot; a steerable trailer connectable to said tractor; an interface member having a bottom surface and an alignment axis, said interface member rotatably connected to said steerable trailer; a kingpin disposed on said bottom surface and on said alignment axis of said interface member; an alignment guide disposed on said interface member, said alignment guide oriented perpendicular to said alignment axis of said interface member, and, said alignment guide having a first end which outwardly projects from said interface member, and an opposite second end which outwardly projects in an opposite direction from said interface member. 11. The alignment system according to claim 10, further including: said first and second ends of said alignment guide being selectively extendable. 12. The alignment system according to claim 10, further including: said first end of said alignment guide having a first planar member having a first edge, said first planar member being oriented parallel to said alignment axis of said interface member; and,said second end of said alignment guide having a second planar member having a second edge, said second planar member being oriented parallel to said alignment axis of said interface member.
