I don't like giving out personal info (or free business) but some companies to look into are: State Farm, Nationwide, Grundy and Hagerty.

Just note, they won't insure only this truck, you'll need a high-value main vehicle with them and/or other policies like an umbrella, house, commercial, etc. And be sure they don't put any restrictions on use (like no offroading, no work/school use, no shopping/errands, etc).

EDIT: Also, all cars are required to be in mint condition when the policy is underwritten. So if there's any rust, damage, paint issues, salvage/accidents, torn leather, etc, I was told they couldn't add it. But that's more because of the main vehicle requirement, which trickles down to all other cars on the policy.
