The fifth wheel hitch assembly may comprise a kingpin receiving assembly attached to a mounting rail via a comfort assembly. The comfort assembly may include one or more pivot bushing assemblies, as well as vertically adjustable, anti-rattle attachment systems. These attachment systems may include a cam assembly and/or a T-pin assembly. ## Claims ### Claim 1 A cam assembly configured to attach a leg of a fifth wheel hitch to a rail, the cam assembly comprising: a foot configured to be operatively inserted into the rail; a cam member comprising a cam barrel engageable with the foot and a cam lever engageable with the cam barrel; a base plate positioned on the foot and configured to engage the rail; and a fastener selectively attached to the foot, wherein the fastener comprises a faucet knob and is selectively positionable along the foot. ### Claim 2 (depends on 1) The cam assembly of claim 1 further comprising a washer positioned between the fastener and the base plate. ### Claim 3 (depends on 1) The cam assembly of claim 1 further comprising a pin engaged with the fastener preventing release of the fastener from the foot. ### Claim 4 (depends on 1) The cam assembly of claim 1 wherein the base plate is configured to engage a leg of a fifth wheel hitch. ### Claim 5 (depends on 1) The cam assembly of claim 1, wherein the fastener is threadably attached to the foot. ### Claim 6 (depends on 1) A fifth wheel hitch attached to a rail via the cam assembly of claim 1. ### Claim 7 (depends on 6) The fifth wheel hitch of claim 6, wherein the fastener is threadably attached to the foot to adjust a distance between the fastener and the rail. ### Claim 8 (depends on 1) The cam assembly of claim 1 further comprising a washer positioned between the fastener and the base plate and a pin engaged with the fastener preventing release of the fastener from the foot. ### Claim 9 (depends on 1) The cam assembly of claim 1, further comprising a fastener adjustably attaching the cam member to the foot. ### Claim 10 A cam assembly configured to attach a leg of a fifth wheel hitch to a rail, the cam assembly comprising: a foot configured to be operatively inserted into the rail; a base plate positioned on the foot and configured to engage the rail; and a cam member selectively attached to the foot, wherein the cam member comprises a cam barrel which selectively engages the foot locking and is configured to adjustably lock the foot to the rail. ### Claim 11 (depends on 10) A fifth wheel hitch attached to a rail via the cam assembly of claim 10. ### Claim 12 A mounting apparatus comprising: a mounting plate configured to engage a leg of a fifth wheel hitch; a plurality of auxiliary components positioned on the mounting plate, wherein at least two of the auxiliary components comprise a different configuration; and at least one T-pin engageable with an underbed hitch mounting system. ### Claim 13 (depends on 12) The mounting apparatus of claim 12, wherein the plurality of auxiliary components comprise a first auxiliary component and a second auxiliary component. ### Claim 14 (depends on 12) The mounting apparatus of claim 12, wherein the T-pin comprises a threaded end and a foot end, wherein the foot end has a pair of elongated opposing shoulders. ### Claim 15 (depends on 13) The mounting apparatus of claim 13, wherein the second auxiliary component comprises: a foot configured to be operatively inserted into a rail; a base plate positioned on the foot and configured to engage the rail; and a fastener selectively attached to the foot, wherein the fastener is selectively positionable along the foot. ### Claim 16 (depends on 13) The mounting apparatus of claim 13, wherein the second auxiliary component comprises: a foot configured to be operatively inserted into a rail; a base plate positioned on the foot and configured to engage the rail; and a cam member selectively attached to the foot, wherein the cam member selectively engages the foot locking and is configured to lock the foot to the rail.
