wherein the floor weighs less than 0.015 lbs per square inch and deflects less than ⅛ th of an inch when 0.14 psi is applied to the entire sidepack floor.

2. The sidepack floor of claim 1 , wherein the first sheet of thermoplastic and the second sheet of thermoplastic are twin sheets of thermoformed thermoplastic formed using twin sheet thermoforming.

3. The sidepack floor of claim 1 , wherein the first sheet of thermoplastic and the second sheet of thermoplastic are fiber reinforced thermoplastic.

4. The sidepack floor of claim 1 , wherein the first sheet of thermoplastic and/or the second sheet of thermoplastic are filled thermoplastics.

5. The sidepack floor of claim 1 , wherein the first sheet of thermoplastic and the second sheet of thermoplastic are formed using injection molding, rotational molding, compression molding, compression molding using unidirectional tape, compression molding using sheet molding compound, compression molding using bulk molding compound, compression molding using thick molding, and/or compression molding using wet molding, gravity fed casting, low pressure casting, high pressure casting, resin transfer molding including light resin transfer molding, 3D printing, extrusion, Digital Light Synthesis (DLS) including Continuous Liquid Infusion Production, vacuum forming, infusion including vacuum infusion, hand layup, infusion, flex molding, lamination, squish molding, chop spray, and/or pultrusion.

6. The sidepack floor of claim 1 , wherein the sidepack floor is molded into a sidepack during manufacture of the sidepack floor.

7. The sidepack floor of claim 1 , wherein the first sheet of thermoplastic and the second sheet of thermoplastic are joined at periodic kiss-off locations.

8. The sidepack floor of claim 1 , wherein the first sheet of thermoplastic and the second sheet of thermoplastic are joined via physical bonding, chemical bonding, mechanical attachment, mechanical interlocking, magnetism, reversible adhesive, irreversible adhesive, welding including plastic welding, infusion, lamination, and/or vacuum attachment.

9. The sidepack floor of claim 1 , further comprising a foam core including a thermoplastic foam core, a polyurethane foam core, a syntactic foam core, a polymethacrylimide (PMI) foam core, a Polyethylene Teraphalate (PET) foam core, a cross linked polyvinyl chloride (PVC) foam core, a linear PVC foam core, and/or a polyester foam core, a honeycomb core, a wood core, a balsa core, a glass fabric core including a 3D woven sandwich glass fabric core, a fiberglass core, a fabric core including laminate bulkers, and/or a carbon core.

10. The sidepack floor of claim 1 , wherein the sidepack floor is integral with a sidepack body.

11. The sidepack floor of claim 1 , wherein the insulating gap is fully encapsulated by the first sheet of thermoplastic and the second sheet of thermoplastic.

12. A sidepack floor comprising:
at least two thermoset panels;
wherein the at least two thermoset panels are manufactured via resin transfer molding, light resin transfer molding, compression molding, compression molding using sheet molding compound, compression molding using bulk molding compound, vacuum infusion, chop spray, pultrusion, injection molding, rotational molding, or hand layup;
wherein the at least two thermoset panels are separated by an insulating gap;
wherein a first thermoset panel and a second thermoset panel of the at least two thermoset panels are joined at periodic kiss-off locations; and
wherein the floor weighs less than 0.015 lbs per square inch and deflects less than ⅛ th of an inch when 0.14 psi is applied to the entire sidepack floor.

13. The sidepack floor of claim 12 , wherein the at least two thermoset panels are joined during manufacture of the at least two thermoset panels via resin transfer molding, light resin transfer molding, compression molding, compression molding using sheet molding compound, compression molding using bulk molding compound, vacuum infusion, chop spray, pultrusion, or hand layup.

14. The sidepack floor of claim 12 , wherein the at least two thermoset panels are fiber reinforced thermoset panels.

15. The sidepack floor of claim 12 , wherein the at least two thermoset panels are filled thermoset panels.

16. The sidepack floor of claim 12 , further comprising at least one thermoplastic material.

17. The sidepack floor of claim 16 , wherein the at least one thermoplastic material includes fiber reinforced thermoplastic material.

18. The sidepack floor of claim 16 , wherein the at least one thermoplastic material includes a filled thermoplastic.

19. The sidepack floor of claim 12 , wherein the sidepack floor is molded into a sidepack during manufacture of the sidepack floor.

20. The sidepack floor of claim 12 , further comprising a honeycomb core, a wood core, a balsa core, a glass fabric core including a 3D woven sandwich glass fabric core, a fiberglass core, a fabric core including laminate bulkers, a carbon core, and/or a foam core including a thermoplastic foam core, a polyurethane foam core, a syntactic foam core, a polymethacrylimide (PMI) foam core, a Polyethylene Teraphalate (PET) foam core, a cross linked polyvinyl chloride (PVC) foam core, a linear PVC foam core, and/or a polyester foam core.

21. The sidepack floor of claim 12 , wherein the at least two thermoset panels are joined via physical bonding, chemical bonding, mechanical attachment, mechanical interlocking, magnetism, reversible adhesive, irreversible adhesive, welding including plastic welding, and/or vacuum attachment.

22. The sidepack floor of claim 12 , wherein the sidepack floor is integral with a sidepack body.
