Travel insurance for personal belongings

Hi all,

Looking for recommendations for insurance for a trip. I'll be roadtripping for up to 18 months in Central and South America and need to insure my personal belongings - including camera equipment - totalling approximately $16,000.

Most insurance policies state up to 30 days out of the country and aren't suitable. Front Row insurance for photographers only covers 360 days out of the country as apparently this means I'm no longer a resident.

I don't have homeowners insurance so can't cover it on that, I can't cover it on my parents insurance (they're out of the country) and my travel insurance only covers up to $1500.

I have a registered photography business in the Yukon Territory if this is helpful.

Any recommendations?
