Вот бы у нас было больше сухих дров и ещё один котелок для супа.

Вот бы introduces a wish. It is similar to if only, I wish, or it would be nice if... It sounds a little emotional and conversational.

The key part is бы, which marks something as wished-for, unreal, or not currently true.

In Russian, wishes and unreal situations are often expressed with бы plus a past-tense verb form. So было is past in form, but not necessarily past in meaning.

English does something similar: I wish we had more firewood. The word had looks past, but the wish is about the present.

Russian usually expresses possession with у plus a form of быть, not with a direct equivalent of English have.

So:

• у нас было = literally something like there was, by us
• natural English = we had

This is a very common Russian pattern:

• У меня есть брат = I have a brother
• У нас было время = We had time

Because the preposition у requires the genitive case. The pronoun мы changes to нас after у.

So:

• мы = we
• у нас = at/by us, which in this structure means we have / we had

This sentence uses an existential/possession pattern: у нас было... In that kind of structure, Russian very often uses было as a general form meaning there was / there were / we had, especially when the sentence is about quantity or availability.

That is especially natural when one of the things mentioned is a quantity phrase like больше сухих дров.

If the sentence only had котелок, you would more likely say:

• Вот бы у нас был ещё один котелок

But in the full sentence, было works as the broader there was/were available form.

After больше meaning more, Russian normally uses the genitive case.

So:

• дрова is the basic dictionary form
• after больше, it becomes дров
• the adjective must match, so сухие becomes сухих

That is why you get:

• больше сухих дров = more dry firewood

Дрова is a plural-only noun in Russian. It refers to firewood as a mass/collective idea, not usually to one single piece.

Its genitive plural form is дров, which appears here because of больше.

So:

• дрова = firewood
• больше дров = more firewood

Ещё один means one more or an additional one.

So ещё один котелок means:

• one more pot
• another pot

This is slightly different from:

• другой котелок = a different pot
• второй котелок = a second pot

Here the idea is we need one extra one.

Котелок usually means a small pot, often a camp pot, mess tin, or something used outdoors over a fire.

In this sentence, with firewood and soup, it strongly suggests a camping or rustic context rather than an ordinary kitchen saucepan.

Для means for and takes the genitive case, so суп becomes супа.

Котелок для супа means a pot for soup or a pot to make/hold soup in. It expresses the purpose of the pot.

Normally, no. Russian usually needs only one бы in this kind of clause.

Here that бы is already present in вот бы, so adding another one after было would sound redundant or wrong in standard usage.

So the natural version is:

• Вот бы у нас было...

not:

• Вот бы у нас было бы...

Russian word order is flexible, but this order is natural.

• Вот бы sets up the wish right away.
• у нас tells you whose situation we are talking about.
• было больше сухих дров и ещё один котелок для супа gives the things being wished for.

So the sentence flows as: If only, in our situation, there were more dry firewood and another pot for soup.

A different order is possible, but this version sounds straightforward and idiomatic.
