I would think that list of implements would weigh in at more than 5500 pounds, but it is just my thoughts. The entire list is considerable more than your picture from the net, and the added stuff is what is costing the extra money, in my opinion. Driving a tractor onto a trailer is easy, loading all that extra stuff is a completely different deal, as far as a trucking company is concerned. Even if the O/P rented a truck, and purchased enough hardware to keep the stuff on the trailer (remember D.O.T requires two per item or blah, blah blah) and actually is aware of how to get the tractor and stuff on the trailer, putting a maxed out trailer load behind a truck that the driver isn't completely used to, and never driven before that weekend, is how a lot of accidents happen.
Yes, I know that everyone has to start sometime, but realistically, there are some people that don't have any business behind the wheel, much less behind the wheel of a maxed out combination rig that they aren't used to. Hopefully the O/P won't take offense at this, because I am NOT SAYING THE O/P can't handle this, I am just pointing out that there is a lot of room for error and some people need to hear it. If the O/P doesn't own the truck and trailer, and isn't used to hauling these types of loads, it might be best for them to bite the bullet and spend the money. One simple mistake can cost way beyond the quoted price for this move.(which quoted price seems a little bit inflated due to the trucking company actually seeing that the chances for a problem are here).
My signature line was written for one mistake that I made and I do have a little bit of experience hauling loads.
