A method of coupling together frame members of a utility vehicle, the method comprising:

• providing a frame assembly comprising a plurality of frame members and a coupler assembly including a plurality of interfaces, wherein the plurality of frame members are angled relative to each other;
• removably coupling a first member of the plurality of frame members to the coupler assembly at first interface of the coupler assembly with at least one removable fastener;
• and
• permanently coupling a second member of the plurality of frame members to the coupler assembly at a second interface of the coupler assembly with a permanent connection.

An upper frame assembly for a utility vehicle, comprising:

• a first frame member;
• a second frame member;
• a coupler assembly having a first interface and a second interface;
• wherein
• the first frame member is removably coupled with a first fastener to the coupler assembly in a first direction at the first interface, the second frame member is permanently coupled with a second fastener to the coupler assembly in a second direction at the second interface, and the first frame member and second frame member are angled relative to each other when coupled to the coupler assembly.
