I believe on the underside of the home you may need to run it in conduit. Read all of this

550.15 Wiring Methods and Materials. Except as specifically
limited in this section, the wiring methods and materials
included in this Code shall be used in mobile homes.
conductors, aluminum alloy conductors, and aluminum
core conductors such as copper-clad aluminum shall not be
acceptable for use as branch-circuit wiring.
(A) Nonmetallic Boxes. Nonmetallic boxes shall be permitted
only with nonmetallic cable or nonmetallic raceways.
(B) Nonmetallic Cable Protection. Nonmetallic cable located
380 mm (15 in.) or less above the floor, if exposed,
shall be protected from physical damage by covering
boards, guard strips, or raceways. Cable likely to be damaged
by stowage shall be so protected in all cases.
(C) Metal-Covered and Nonmetallic Cable Protection.
Metal-covered and nonmetallic cables shall be permitted to
pass through the centers of the wide side of 2 by 4 studs.
However, they shall be protected where they pass through
2 by 2 studs or at other studs or frames where the cable or
armor would be less than 32 mm (11⁄4 in.) from the inside
or outside surface of the studs where the wall covering
materials are in contact with the studs. Steel plates on each
side of the cable, or a tube, with not less than 1.35 mm
(0.053 in.) wall thickness shall be required to protect the
cable. These plates or tubes shall be securely held in place.
(D) Metal Faceplates. Where metal faceplates are used,
they shall be grounded.
(E) Installation Requirements. Where a range, clothes
dryer, or other appliance is connected by metal-covered cable
or flexible metal conduit, a length of not less than 900 mm
(3 ft) of unsupported cable or conduit shall be provided to
service the appliance. The cable or flexible metal conduit shall
be secured to the wall. Type NM or Type SE cable shall not be
used to connect a range or dryer. This shall not prohibit the use
of Type NM or Type SE cable between the branch-circuit
overcurrent protective device and a junction box or range or
dryer receptacle.
(F) Raceways. Where rigid metal conduit or intermediate
metal conduit is terminated at an enclosure with a locknut and
bushing connection, two locknuts shall be provided, one inside
and one outside of the enclosure. Rigid nonmetallic conduit,
electrical nonmetallic tubing, or surface raceway shall be
permitted. All cut ends of conduit and tubing shall be reamed
or otherwise finished to remove rough edges.
(G) Switches. Switches shall be rated as follows:
(1) For lighting circuits, switches shall be rated not less
than 10 amperes, 120 to 125 volts, and in no case less
than the connected load.
(2) Switches for motor or other loads shall comply with the
provisions of 404.14.
(H) Under-Chassis Wiring (Exposed to Weather). Where
outdoor or under-chassis line-voltage (120 volts, nominal,
or higher) wiring is exposed to moisture or physical damage,
it shall be protected by a conduit or raceway approved
for use in wet locations or where subject to physical damage.
The conductors shall be listed for use in wet locations.

As far as I can tell, the only wiring allowed under a manufactured home is PVC & UF/thhwn.

Pain in the butt!
Commit to the Lord whatever you do, and your plans will succeed.
