I reached out to a friend who has a PM company, but they require all contractors be insured.

If your insurance coverage isn't enough, they could seize the LLC assets but not your personal assets.Additional thoughts:1.

I worked for a US retail company that had a policy of accepting returns no questions asked and even when I accidentally uncovered someone seriously abusing the policy, my bosses wouldn't pursue the matter. 

When I first started out, I was insuring everything with USAA.

But it sounds like you are talking about a life insurance retirement plan (LIRP).

Using a Whole Life Insurance (WLI) loan avoids banks but accrues interest, potentially reducing policy benefits—compare this with other financing options like HELOC or seller financing.

I'm having trouble getting the insurance provider I usually use for my SFH to give me a quote for a trailer park I'm interested in.

If so, you should also look into the insurance requirements during construction (both builder risk as well as the GC's policy, but particularly the GC policy).

As a medium-term rental, you'd be in better position to be connected with Insurance Company that way.
