Ground power options

120V ONLY

30A RV receptacle......
1 HOT
1 Neutral
1 Ground wire

Do NOT have it wired for 240V
2 Hots and a 1 Neutral
That will cause an 'electrocution' of ALL 120V components/and electronics in your TC

NOTHING in a RV is 220 volts. A properly wired 50A RV outlet has two 110V hot lines, which if are properly connect, will have 220v across them. Each side is 110v ONLY to the ground or neutral connection. Each 110v side has a 30-50A breaker, which allows up to 50A on each let. There is NO increase in voltage. Trying to connect any 220V appliance across the two legs will only produce disaster. Many Campgrounds actually have the same 110V wire connected to both sides of the 50A connector, which will provide exactly the same results for the RV.
However, as I am an registered OLD Fart, and it is common knowledge that many of us don't have any idea what we are talking about in the "MODERN" world, It is possible that some things may have changed, and I could be completely wrong. In that case I will not get my feelings hurt at all if some brilliant youngster that knows everything about everything tells you anything different.

Old-Biscuit, I really like the diagram you posted. Is there another one that shows the 50A rv connector??

220V is just 2x 110V les with a ground and optional neutral. I assumed that my little 45A panel would have no use for 220V, but you've pretty much confirmed that.

This is a standard NEMA 14-50 used in homes for a range/stove/oven

YEP.......

That's the one for RVs NEMA 14-50R :B

110/220 volts went out with the buggy whip. Standard voltage now is 120/240

What about 208V AC?

208 is the voltage between two legs of three phase power found in many commercial buildings.
Still 120v to neutral so an RV park can use this power for the pedestals.
Not very common in the RV world. Either way it is not 110 even if most refer to this old nomenclature.

The reason I ask is I'm going to add an outlet on the side of my house and can provide either 110V or 220V. If 220V works and would charge faster that would be good to know. If I'd burn something down, I guess that might be good too.

You will burn something down feeding 240 in to your truck camper's 120v electrical system.

It won't charge up faster because everything will burn up.

Your outside house outlet would need to be either a 120 volt outlet or a 240 volt.
