The storage tank is configured to be arranged in at least two positions. The at least two positions include a first position in which the storage tank is arranged parallel to a surface, and a second position in which the storage tank is arranged perpendicular to the surface. A walkway may be positioned in the interior cavity of the body. ## Claims ### Claim 1 A vertical fluid storage tank, comprising: a body extending from a first end to a second end defining an interior cavity and having an oval-shaped cross-section; a top wall connected to the first end of the body; a bottom wall connected to the second end of the body; and a frame member connected to an exterior surface of the body, the frame member including a first portion that extends longitudinally along the body and a second portion that extends along the bottom wall and is connected to the first portion such that the bottom wall of the body is located on the second portion of the frame member, wherein the fluid storage tank is configured to be arranged in at least two positions, the at least two positions comprising a first position in which the fluid storage tank is arranged parallel to a surface, and a second position in which the fluid storage tank is arranged perpendicular to the surface, wherein the frame member remains connected to the fluid storage tank when the fluid storage tank is moved between the at least two positions; and wherein an outermost width of the first portion is less than an outermost width of the bottom wall of the body. ### Claim 2 (depends on 1) The vertical fluid storage tank as claimed in claim 1, the frame member comprising a ladder extending in a longitudinal direction relative to the body. ### Claim 3 (depends on 1) The vertical fluid storage tank as claimed in claim 1, the frame member comprising a walkway extending across the top wall of the storage tank. ### Claim 4 (depends on 1) The vertical fluid storage tank as claimed in claim 1, further comprising a walkway positioned in the interior cavity of the body. ### Claim 5 (depends on 1) The vertical fluid storage tank as claimed in claim 1, wherein the frame member is L-shaped with the first portion extending along the longitudinal length of the body and the second portion extending along the bottom wall of the storage tank. ### Claim 6 (depends on 1) The vertical fluid storage tank as claimed in claim 1, wherein the first portion of the frame is fixedly connected to the body and the second portion is fixedly connected to the body. ### Claim 7 (depends on 1) The vertical fluid storage tank as claimed in claim 1, wherein the oval-shaped cross section is defined by a major diameter and a minor diameter, the major diameter being greater than the minor diameter, and wherein, in the first position, the major diameter extends perpendicular to the surface and the minor diameter extends parallel to the surface. ### Claim 8 (depends on 7) The vertical fluid storage tank as claimed in claim 7, wherein the minor diameter of the cross section of the body is greater than an outermost width of the frame member. ### Claim 9 The vertical fluid storage tank as claimed in 1, wherein the frame member includes a coupling for attaching the fluid storage tank to a hitch of a vehicle. ### Claim 10 The vertical fluid storage tank as claimed in 1, wherein the first portion of the frame member is immovably connected to the second portion of the frame member. ### Claim 11 A vertical fluid storage tank, comprising: a body extending from a first end to a second end defining an interior cavity and comprising an oval-shaped cross-section; a top wall connected to the first end of the body; a bottom wall connected to the second end of the body; and a frame member connected to an exterior surface of the body, the frame member including a first portion that extends longitudinally along the body and a second portion that extends along the bottom wall and is connected to the first portion such that the bottom wall of the body is located on the second portion of the frame member, wherein an outermost width of the first portion is less than or equal to an outermost width of the bottom wall of the body, and wherein the fluid storage tank is configured to be arranged in at least two positions comprising a first position in which the fluid storage tank is arranged parallel to a surface, and a second position in which the fluid storage tank is arranged perpendicular to the surface. ### Claim 12 (depends on 11) The vertical fluid storage tank as claimed in claim 11, the frame member comprising a ladder extending in a longitudinal direction relative to the body. ### Claim 13 (depends on 11) The vertical fluid storage tank as claimed in claim 11, the frame member comprising a walkway extending across the top wall of the storage tank. ### Claim 14 (depends on 11) The vertical fluid storage tank as claimed in claim 11, further comprising a walkway positioned in the interior cavity of the body. ### Claim 15 (depends on 11) The vertical fluid storage tank as claimed in claim 11, wherein the frame member is L-shaped with the first portion extending along the longitudinal length of the body and the second portion extending along the bottom wall of the storage tank. ### Claim 16 (depends on 11) The vertical fluid storage tank as claimed in claim 11, wherein the first portion of the frame is fixedly connected to the body and the second portion is fixedly connected to the body. ### Claim 17 (depends on 11) The vertical fluid storage tank as claimed in claim 11, wherein the oval-shaped cross section is defined by a major diameter and a minor diameter, the major diameter being greater than the minor diameter, and wherein, in the first position, the major diameter extends perpendicular to the surface and the minor diameter extends parallel to the surface. ### Claim 18 (depends on 17) The vertical fluid storage tank as claimed in claim 17, wherein the minor diameter of the cross section of the body is greater than an outermost width of the frame member. ### Claim 19 The vertical fluid storage tank as claimed in 11, wherein the frame member includes a coupling for attaching the fluid storage tank to a hitch of a vehicle. ### Claim 20 The vertical fluid storage tank as claimed in 11, wherein the first portion of the frame member is immovably connected to the second portion of the frame member.
