A chassis frame has a right side rail and a left side rail running lengthwise of the frame opposite each other and joined together by at least one crossmember. A rectangular tube overlies, and has underlying support by, the top wall of the respective side rail. A right uniting member runs lengthwise of the frame for uniting the right rectangular tube and the right side rail in assembly, and a left uniting member runs lengthwise of the frame for uniting the left rectangular tube and the left side rail in assembly. Each uniting member has a horizontal flange overlying and joined to the respective rectangular tube, and a vertical flange extending downward from the respective horizontal flange and joined to the respective side rail.

1. A chassis frame comprising: a right side rail running lengthwise of the frame,a left side rail running lengthwise of the frame,the right and left side rails being opposite each other and joined together by at least one crossmember,each side rail comprising a channel which has an interior bounded
1. A chassis frame comprising: a right side rail running lengthwise of the frame,a left side rail running lengthwise of the frame,the right and left side rails being opposite each other and joined together by at least one crossmember,each side rail comprising a channel which has an interior bounded by a vertical wall and by horizontal top and bottom walls which extend from top and bottom of the vertical wall toward the top and bottom walls of the opposite side rail,a right rectangular tube,a left rectangular tube,each rectangular tube overlying, and having underlying support by, the top wall of the respective side rail,a right uniting member running lengthwise of the frame for uniting the right rectangular tube and the right side rail in assembly, anda left uniting member running lengthwise of the frame for uniting the left rectangular tube and the left side rail in assembly,each uniting member having a horizontal flange overlying and joined to the respective rectangular tube, and a vertical flange extending downward from the respective horizontal flange and joined to the respective side rail. 2. The chassis frame as set forth in claim 1 further comprising a plate which extends lengthwise of the frame, which has a lengthwise left margin overlying, and having underlying support by, the left rectangular tube, and which has a lengthwise right margin overlying, and having underlying support by, the right rectangular tube. 3. The chassis frame as set forth in claim 2 in which the side rails extend lengthwise forwardly beyond a forward lengthwise terminus of the plate, the rectangular tubes, and the uniting members, and further comprising a cab having an occupant compartment mounted on the side rails forwardly of the forward lengthwise terminus of the plate, the rectangular tubes, and the uniting members. 4. The chassis frame as set forth in claim 3 in which the side rails extend lengthwise rearwardly beyond a rearward lengthwise terminus of the plate, the rectangular tubes, and the uniting members. 5. The chassis frame as set forth in claim 4 further comprising a drive axle suspended from the frame by a suspension which comprises right side brackets disposed against the vertical flange of the right uniting member and fastened to the frame by fasteners passing through holes in the vertical flange of the right uniting member and the vertical wall of the right side rail and left side brackets disposed against the vertical flange of the left uniting member and fastened to the frame by fasteners passing through holes in the vertical flange of the left uniting member and the vertical wall of the left side rail. 6. The chassis frame as set forth in claim 4 in which a first crossmember is fastened to the right side rail and the left side rail at a lengthwise location forward of the forward lengthwise terminus of the plate, the rectangular tubes, and the uniting members, a second crossmember is fastened to the right side rail and the left side rail at a lengthwise location rearward of the rearward lengthwise terminus of the plate, the rectangular tubes, and the uniting members, and a third crossmember is disposed between the right side rail and the left side rail at a lengthwise location between the first crossmember and the second crossmember and is fastened in place by fasteners which pass through aligned holes in the right side rail and the right uniting member and by fasteners which pass through aligned holes in the left side rail and the left uniting member. 7. The chassis frame as set forth in claim 6 in which the third crossmember comprises two parts having central zones which are fastened together, each part comprising a pair of legs which diverge from each other in directions away from the central zone and which have free ends via which the two parts are fastened in place. 8. The chassis frame as set forth in claim 2 comprising a weldment which joins the lengthwise left margin of the plate to both the left rectangular tube and the top horizontal wall of the left side rail and a weldment which joins the lengthwise right margin of the plate to both the right rectangular tube and the top horizontal wall of the right side rail. 9. The chassis frame as set forth in claim 8 comprising fasteners which join together the vertical flange of each uniting member and the vertical wall of the respective side rail. 10. The chassis frame as set forth in claim 8 comprising a weld which joins together the vertical flange of each uniting member and the respective rectangular tube. 11. The chassis frame as set forth in claim 2 in which the vertical flange of each uniting member extends downwardly beyond the bottom wall of the respective side rail, and each uniting member further comprises an underlying horizontal flange extending from the uniting member's vertical wall in underlying relation to the bottom wall of the respective side rail. 12. The chassis frame as set forth in claim 11 in which each underlying horizontal flange is spaced from and unattached to the bottom wall of the respective side rail. 13. The chassis frame as set forth in claim 2 in which the side rails extend lengthwise forwardly beyond a forward lengthwise terminus of the plate, the rectangular tubes, and the uniting members, the frame comprises a cab mount crossmember located forwardly of the forward lengthwise terminus of the plate, the rectangular tubes, and the uniting members, and a cab having an occupant compartment is disposed on the frame forwardly of the forward lengthwise terminus of the plate, the rectangular tubes, and the uniting members, and is supported by a cab mount on the cab mount crossmember. 14. The chassis frame as set forth in claim 13 in which the frame comprises at least two more crossmembers disposed between the side rails rearward of the cab mount cross member. 15. The chassis frame as set forth in claim 14 in which at least one of the at least two more crossmembers is beneath the plate.
