Last time I did the short term, I got a months insurance from State Farm. They will not cover it themselves, but have a commercial underwriter do it for them. The big guys can usually do this the easiest.
Remember to tell them very low mileage per month/year, as that really drops the cost of it (or, it did for me anyways.... )
As for shipping, best bet, call around to some local places that haul out, and see if any have some open space on back hauls. THAT is how you save a LOT of money on shipping.
As for going rates, I only know what I charge as a tow truck. And that would be an outrageous quote for the mileage you are talking about!
Great points Ed! I hadn't thought of the short term insurance option.
Tony,
To expand a little using a commercial carrier to ship the truck------------
Be sure to tell them up front it'll be oversize. There's usually an additional fee for permits and such. You may luck out and find one that'll take it to pay for fuel to get home or closer to the next load.
The bridge truck will require a step deck trailer (usaully a 48 footer, with a 37 ft bottom deck and an 11 ft top deck) as it's too tall for a standard flatbed unless the stack's removed, and the windshield's folded down . (Big pain in the posterior) The better option would be a lowboy type of trailer the truck can be driven onto on site as opposed to a step deck that requires a ramp. The down side to this is it'd cost more as it's more specialised equipment.
As for insurance, I've never done short term. The 5 ton's insured thru Gulfway in Florida, an agent/broker for Travelers as a collector/historic vehicle. They don't require vehicles to be parked indoors or a secure area like Hagerty and others. My rate is about $238.00 p/yr for full coverage, and PIP. They require photos from all four sides, interior shots, a bunch of questions about usage, other drivers in the household and a mileage report in a yearly update. The Blazer's insured thru another company as a regular vehicle.
Hope my nickels worth helped a bit.
