Abstract

A recreational vehicle may include a chassis, an axle assembly, a floor, and a vehicle body enclosing living quarters. A fluid storage vessel may be supported in the chassis. The chassis may include a first and a second longitudinal chassis member each having an upper and lower edge, and an inner and outer face. Cross members have a first and second ends connected to the first and second chassis member, respectively. The cross members have an upper and lower edges extending between the ends. The cross members have an end height at the ends and a midsection height that is greater than the end height. A transport area extends longitudinally between two cross members, transversely between inner faces of the longitudinal chassis members, and vertically between upper and lower edges of the cross members. The fluid storage vessel is disposed in the transport area.

First claim

What is claimed is:

1. A recreational vehicle of the type having living quarters defined therein, the recreational vehicle comprising:
a chassis;
an axle assembly coupled to the chassis and providing motive support and underbody clearance to the chassis;
a floor defining a lower limit of the living quarters;
a vehicle body generally enclosing the living quarters, the vehicle body and the floor being supported by the chassis; and
at least one fluid storage vessel supported in the chassis;
wherein the chassis comprises;

a first and a second longitudinal chassis member each having an upper edge and a lower edge, and an inner face and an outer face; and
a plurality of cross members each having a first end connected to the first longitudinal chassis member and a second end connected to the second longitudinal chassis member such that the plurality of cross members extend between and interconnect the first and second longitudinal chassis members, each of the plurality of cross members having an upper edge and a lower edge extending between the first and second ends;
wherein each of the plurality of cross members has an end height defined as a vertical distance between the lower edge and upper edge at the first and second ends and a midsection height defined as a vertical distance between the lower edge and upper edge of a midsection of each of the plurality of cross members, the midsection height being greater than the end height; and

wherein a transport area extends longitudinally between two of the plurality of cross members, transversely between inner faces of the first and second longitudinal chassis members, and vertically between upper and lower edges of the two cross members, the at least one fluid storage vessel being disposed in the transport area.

2. The recreational vehicle according to claim 1 , wherein:
the upper edge of each the plurality of cross members at the first end is proximate the upper edge of the first longitudinal chassis member;
the upper edge of each of the plurality of cross members at the second end is proximate the upper edge of the second longitudinal chassis member; and
the midsection height of each of the plurality of cross members is greater than a vertical height of the longitudinal chassis members.

3. The recreational vehicle according to claim 2 , wherein the floor is disposed on the upper edges of the plurality of cross members.

4. The recreational vehicle according to claim 2 , wherein the lower edge of each the plurality of cross members at the first end is proximate the lower edge of the first longitudinal chassis member and the lower edge of each of the plurality of cross members at the second end is proximate the lower edge of the second longitudinal chassis member.

5. The recreational vehicle according to claim 1 , wherein the at least one fluid storage vessel is a tank.

6. The recreational vehicle according to claim 1 , further comprising a belly pan disposed on and extending longitudinally between the lower edges of the plurality of cross members and extending transversely between the first and second longitudinal chassis members.

7. The recreational vehicle according to claim 1 , wherein the upper edge of each of the plurality of cross members is straight end-to-end.

8. The recreational vehicle according to claim 1 , wherein the midsection of each of the plurality of cross members spans a majority of a length of the cross members, the lower edge of the midsection being straight end-to-end.

9. The recreational vehicle according to claim 8 , wherein each of the plurality of cross members has a first and second end portion, and the lower edge of the end portions is angled or curved between the respective ends of the cross member and the lower edge of the midsection.

10. The recreational vehicle according to claim 1 , wherein the chassis further comprises at least one additional cross member extending between the first and second longitudinal chassis members, the at least one additional cross member having a lower edge that is straight end-to-end.

11. The recreational vehicle according to claim 1 , wherein each of the plurality of cross members is a stamped member having an upper flange defining the upper edge and a lower flange defining the lower edge, each flange extending generally perpendicularly to a generally vertical face of the cross member.

12. The recreational vehicle according to claim 11 , wherein each of the plurality of cross members further comprises an intermediate flange extending end-to-end and positioned between the upper and lower flanges, the intermediate flange being straight end-to-end.

13. The recreational vehicle according to claim 12 , wherein each cross member has a first piece extending from the upper flange to the intermediate flange and a second piece extending from the intermediate flange to the lower flange, the first and second pieces being interconnected to form the cross member.

14. The recreational vehicle according to claim 1 , wherein each of the plurality of cross members has at least one opening in a vertical face of the cross member.

15. The recreational vehicle according to claim 1 , wherein each of the plurality of cross members has an upper member defining the upper edge, a lower member, and a plurality of rods extending between and interconnecting the upper and lower members.

16. The recreational vehicle according to claim 1 , wherein the at least one fluid storage vessel has a maximum height approximately equal to the midsection height.

17. The recreational vehicle according to claim 1 , wherein the at least one fluid storage vessel has a lower surface disposed at or above the lower edges of the plurality of cross members and an upper surface at or below the upper edges of the plurality of cross members.

18. The recreational vehicle according to claim 1 , wherein the recreational vehicle is a towable trailer without a powertrain.
