Personal travel insurance to cover while driving

I want to make sure my stuff is covered while working abroad.

I’ll be overseas for up to 60 days in a go so no use cover on a 30 or 45 day limit, and must not exclude travel related to business, or exclude self employed people.

must NOT identify a lap-top as “valuables” and must allow living in a truck as opposed to hotels.

any recommendations for decent insurance co’s ?
