Insurance depends on what you need to insure your vehicle for...When we first bought ours it was like $380 per month because truck was insured for over hundred fifteen thousand or so. Now ours runs about $260 for $75,000. This includes bob tail. Lots of people use OIDIA for insurance, we don't, hopefully some who does will see this post.
