2. The vehicle chassis of claim 1 , wherein the subassembly is further coupled to the first front vertical support and the second front vertical support.
3. The vehicle chassis of claim 1 , wherein the first front vertical support comprises a lower front curved portion and the first rear vertical support comprises a lower rear curved portion, and wherein the lower front curved portion and the lower rear curved portion are configured to partially surround a fuel tank.
4. The vehicle chassis of claim 1 , wherein the first rear vertical support comprises a rear middle curved flange configured to partially surround a fuel tank.
5. The vehicle chassis of claim 1 , further comprising:
a second plug-end fuel tank bracket coupled to the first front outside vertical member and the first rear outside vertical member at a vertical position higher than the first valve-end fuel tank bracket; and
a second valve-end fuel tank bracket coupled to the second front outside vertical member and the second rear outside vertical member at a vertical position higher than the first plug-end fuel tank bracket.
6. The vehicle chassis of claim 5 , further comprising:
a third valve-end tank bracket coupled to the first front outside vertical member and the first rear outside vertical member at a vertical position higher than the second plug-end fuel tank bracket; and
a third plug-end tank bracket coupled to the second front outside vertical member and the second rear outside vertical member at a vertical position higher than the second valve-end fuel tank bracket.
7. A system for mounting fuel storage tanks to a vehicle, the system comprising:
a first front outside vertical member coupled to a first rear outside vertical member by a first valve-end fuel tank bracket and a first plug-end fuel tank bracket;
a second front outside vertical member coupled to a second rear outside vertical member by a second plug-end fuel tank bracket and a second valve-end fuel tank bracket;
a first front vertical support comprising a first lower front curved portion coupled to a first rear vertical support comprising a first lower rear curved portion, wherein the first lower front curved portion and the first lower rear curved portion are configured to partially surround a fuel tank;
a second front vertical support comprising a second lower front curved portion coupled to a second rear vertical support comprising a second lower rear curved portion, wherein the second lower front curved portion and the second lower rear curved portion are configured to partially surround the fuel tank;
an upper front lateral member coupled to the first front outside vertical member, the first front vertical support, the second front outside vertical member, and the second front vertical support;
a first lateral bracket having a first outer longitudinal arm coupled to the first front outside vertical member and the first rear outside vertical member, a first front mounting bracket, and a first rear mounting bracket;
a second lateral bracket having a second outer longitudinal arm coupled to the second front outside vertical member and the second rear outside vertical member, a second front mounting bracket, and a second rear mounting bracket; and
a subassembly coupled to the first front outside vertical member and the second front outside vertical member,
wherein the upper front lateral member is a part of the subassembly, and
wherein the subassembly comprises a main bar having a first bend adjacent a first end of the main bar and a second bend adjacent a second end of the main bar.
8. The system of claim 7 , wherein the first rear vertical support further comprises a rear middle curved flange configured to partially surround the fuel tank.
9. The system of claim 7 , wherein the second plug-end fuel tank bracket is coupled to the first front outside vertical member and the first rear outside vertical member at a vertical position higher than the first valve-end fuel tank bracket, and
wherein the second valve-end fuel tank bracket is coupled to the second front outside vertical member and the second rear outside vertical member at a vertical position higher than the first plug-end fuel tank bracket.
10. The system of claim 9 , further comprising:
a third valve-end fuel tank bracket coupled to the first front outside vertical member and the first rear outside vertical member at a vertical position higher than the second plug-end fuel tank bracket; and
a third plug-end fuel tank bracket coupled to the second front outside vertical member and the second rear outside vertical member at a vertical position higher than the second valve-end fuel tank bracket.
