Thank you. The reason may be that "my trucks" is a single idea and
also that the use of "it" sharpens the impact.

It is correct because "trucks" are viewed as a unit tied up with "my
business" in the relative clause, which, of course, is also singular.
That's why "it is" is correct.

Does that also explain _It is basically my trucks on which my two business
depend_?

That should have been, obviously, _It is basically my trucks on which my
two businesses depend_.
[I'm starting to agree with Mark Wallace's proposal last year about
abolishing plural and singular in English. It makes sense!]

Well, that's one way to look at it -- but I don't agree. This use of
a singular dummy subject is a consequence of idiom, not any sort of
semantics. This is easy to prove, because reordering the sentence
reveals the plural nature of what follows "It is": "My trucks *are*
what my business depends on." The trucks are no more or less a unit
in this syntax than they are in the cleft ("It is") version, but you
don't hear many people saying "My trucks *is* what my business
depends on." (I'd wager that you'd have a chance at getting "is" in
that version only if you told your interlocutor in advance that you
wanted to know which verb form to use.)
A different reordering produces this: "My business depends on my
trucks." But here "my trucks" is the object and you don't have to
make a choice of number. And, as John Flynn implies, pluralizing
"business" pluralize the verb: "My businesses *depend* on my
trucks." So there's no "unit" there.
And what do you do with "What my business depends on is/are my
trucks"? Do you use a singular verb to go with "what" or a plural
verb to go with "my trucks." Is "what" the subject, by virtue of
its actual placement, or "my trucks" by virtue of its being the
natural subject if the sentence isn't inverted? The answer to that
one is that you have your choice. Either will sound right to some
people and wrong to others.
But idiom is in control here, not meaning.
