Hello, Im planning on bringing temporary power to a tiny house mounted on a metal trailer frame from a generator. Few questions, Would the best insulation for the supply cable be SOOW? Im planning on driving ground rods at the generator and at the tiny house with #6 bare copper. Should i bond to the frame of the trailer with an insulated #6 as well? Lastly, the nueutral and ground busses should still be boned at the panel for the tiny house correct?

Water-resistant exercise-bicycle generator goes in shower stall, so the tankless water heater has enough power for luke-warm bathing.

It is sad that a legitimate request is met with smarty balderdash.

OK with approved cords that meet suitability.

Since this is a temporary setup you are only required to make grounding provision at the generator unit up to line side of the disconnect. . . never at the load side. (NEC 551-16)

No, the neutral should not be bonded to the frame. If the neutral bus is bonded to the metal enclosure of the distribution panel, the bonding wire should be removed along with any pigtails in the branch circuits. (if there is any.) (NEC 551-24 .)

I suggest you peruse Art. 551 that covers mobile homes.

may i ask, what do you mean by pig tails in the branch circuit

Or if the wheels stay on it, is it considered an RV? Though with possible 240V loads...

The wheels staying on or off would not in itself distinguish a mobile home from an rv.

If these are being built as mobile homes this would take you back to mobile homes prior to the fair housing act regulating manufactured homes

550.1 Scope.
The provisions of this article cover the electrical conductors and equipment installed within or on mobile and manufactured homes, the conductors that connect mobile and manufactured homes to a supply of electricity, and the installation of electrical wiring, luminaires, equipment, and appurtenances related to electrical installations within a mobile home park up to the mobile home service-entrance conductors or, if none, the mobile home service equipment.

If you have wired an RV, some outlet devices are mounted in metal boxes that are either welded or screwed to the metal frame. The constant movement of the vehicle and temperature extremes cause loosening of any secured mounting devices. These boxes have provision for pigtails for bonding.

This is covered by RVIA (Recreational Vehicle Industry Association) that oversees quality of electrical wiring in RVs.
This is what LA City Electrical code inspectors along with NEC base their procedure in conducting inspection.
I have an RV and replaced each one with newer models 3x and I had to go through their tests.

there should be a # 6 copper main bonding jumper ran from the equipment ground bus to the metal frame

It reminds me the portable type genset.

From what I read here no. The frame is the ground because the gen is bonded.

Now I have to read more and see if my gen is correct because I go into a transfer switch.

I did not take the question about bonding the metal frame to be about the Generator frame at all.

I took the question about bonding from the distribution panel in the tiny home mounted on a metal frame.

I would say yes, you would need to bond the metal frame that the home is mounted on to the equipment ground terminal buss in the in the trailer homes distribution panel.

Anything smaller than a 6 AWG would need additional physical protection

So bond the equipment ground buss in the trailer home to the trailer frame
