i need a 30 day insurance

Even if it you got it towed Lone Mountain isn't going to let you leave without Physical Damage and gap. Many places sell it. OOIDA has a liability product for what you're doing as well as the physical damage (I've used them for 12+ years for PD), or like another said, the company you're leasing to might give you the liability insurance if you're far enough in the process.

 

I've bought 3 trucks now, each time I have used this company. It wasn't "cheap" but it got my truck home and then to the carrier I was leasing on to. The rate is based on the value of the truck.

When I moved one of the trucks from one company to another, I set up everything on the phone for insurance permits and so on and had them send it all to me FedEx next day. Then I had everything ready when I took it to get the signs put in and inspected.
