First and second support arms depend from the first and second mounting arms and support one or more mud flaps so that the mud flaps are positioned behind the rearward wheels of the vehicles and substantially across the space between the rearward wheels. A leash or brace are provided for structural stability and to secure the system with the tow assembly. A central mud flap may be provided in horizontal or vertical configurations according to the desired flow of matter beneath the vehicle. ## Claims ### Claim 1 A mud flap system for use with a vehicle having a tow assembly with a tubular, transverse frame with opposing open end portions and a receiver, the system comprising: first and second mounting arms, having engagement end portions that are shaped and sized to be operatively coupled with the opposing end portions of the transverse frame; first and second support members, depending from said first and second mounting arms in a generally parallel, spaced-apart manner; and at least one mud flap operatively coupled with said first and second support members so that, when said first and second mounting arms are operatively coupled with the opposing end portions of the transverse frame, at least one mud flap is positioned adjacent the transverse frame, substantially across a length that extends between the opposing end portions of the transverse frame. ### Claim 2 (depends on 1) The system of claim 1 wherein said first and second support members are formed as separate structural members. ### Claim 3 (depends on 1) The system of claim 1 further comprising first and second spacing arms disposed between the first mounting arm and first support member and second mounting arm and second support member, respectively, to position said first and second mounting arms in a spaced-apart relationship with said first and second support members. ### Claim 4 (depends on 1) The system of claim 1 wherein said first and second mounting arms are sized and shaped to be at least partially slidably received within the opposing open end portions of the tow assembly. ### Claim 5 (depends on 2) The system of claim 2 further comprising securement means for operatively coupling said first and second support members with one another in a manner that limits movement of said first and second support members with respect to one another. ### Claim 6 (depends on 5) The system of claim 5 wherein said securement means further assists in preventing said first and second mounting arms from becoming unintentionally uncoupled with the opposite end portions of the transverse frame. ### Claim 7 (depends on 5) The system of claim 5 wherein said securement means is comprised of an elongated, generally flexible leash having opposite end portions. ### Claim 8 (depends on 5) The system of claim 5 wherein said securement means is comprised of a brace that operatively and releasably couples interior end portions of said first and second support members with one another. ### Claim 9 (depends on 8) The system of claim 8 wherein said interior end portions of said first and second support members are provided with openings, which are in communication with interior cavities within said first and second support members, and said brace is provided with opposite end portions that are sized and shaped to be selectively positioned through said openings into said interior cavities. ### Claim 10 (depends on 8) The system of claim 8 wherein said brace is provided with open opposite end portions that are in communication with an interior cavity and the interior end portions of said first and second support members are sized and shaped to be selectively positioned through said openings into said interior cavity. ### Claim 11 (depends on 8) The system of claim 8 wherein the interior end portions of said first and second support members and opposite end portions of said brace are selectively engageable with one another in a manner that permits said first and second support members to be secured in a static position with respect to one another at variable distances apart from one another so that the system may be adjusted for use with various tow assemblies having transverse frames of various lengths. ### Claim 12 (depends on 9) The system of claim 9 further comprising a plurality of lock pins that are selectively disposed at least partially through said first and second support members and the opposite end portions of said brace so that said first and second support members are secured in position with respect to one another. ### Claim 13 (depends on 10) The system of claim 10 further comprising a plurality of lock pins that are selectively disposed at least partially through said first and second support members and the opposite end portions of said brace so that said first and second support members are secured in position with respect to one another. ### Claim 14 (depends on 10) The system of claim 10 wherein at least one mud flap is provided as a first mud flap operatively coupled with said first support member, a second mud flap operatively coupled with said second support member and a third mud flap operatively coupled with said brace. ### Claim 15 (depends on 14) The system of claim 14 wherein said third mud flap has opposite side edge portions that are positioned closely adjacent interior edge portions of said first and second mud flaps when said first and second mounting arms are coupled with the opposite end portions of the transverse frame. ### Claim 16 (depends on 14) The system of claim 14 wherein said third mud flap is coupled with said brace along an upper edge portion of said third mud flap and a lower edge portion of said third mud flap is removably coupled with a portion of a trailer that is coupled with the tow assembly so that said third mud flap is generally horizontally disposed. ### Claim 17 (depends on 16) The system of claim 16 wherein said first and second mud flaps are generally horizontally disposed, behind rear wheels of the vehicle, so that air and debris flowing under the vehicle may freely pass between said first and second mud flaps and beneath said horizontally disposed third mud flap.
