Yes it does. In the USA, almost all tolls are simply based on the number of axles. If your pick up truck or SUV has four axles, and the trailer you are towing has two axles, then you will be charged the six axle rate. The price is different everywhere you go. Check the local website for the DOT of the state you are driving in.
The cost of a used trailer depends on the type and condition of the trailer itself. The average price is about five thousand dollars or more for a trailer in new or nice condition.
There is such a wide variety of trailer classes and types that you'd have to be a LOT more specific in what you think an "average" trailer is.
If the round about question is how much does a trailer cost then what type of trailer...flatbed, refrigerated, dry van, car hauler, ect. Cost ranges between $30,000 and $100,000. Specialized trailers can be substantially more.
A basic steel enclosed trailer for cattle or horses can easily cost USD$3,000 to $4.000. A fancier model with drop feed door and more comfort for livestock can cost up to USD$15,000.
Yes! i have towed many times with a Honda Element. The real issue is weight though and I would not put more then 1000lbs in that trailer.
If you are driving a loaded tractor trailer, you would downshift to gain more power when going up hill and downshift to control speed when going down hill.
44,000 is more like the limit on a tandem trailer.
No. Trailer parks are no more likely to be hit than any other patch of land of the same size. However, because trailer homes are weakly built and often not tied down, they are more easily destroyed. A trailer home can be completely destroyed by a tornado that would only remove the roof of a typical site-built house. The means that a tornado that hits a trailer park will generally cause more severe damage and is more likely to kill or seriously injure people and therefore more likely to attract media attention.
If you have enough people, you could lift it manually. For lifting wheels, though, a jack is more common.
If there are more of its kind then no. It is dead though.
The cost of living never goes down.
Yes. More material means higher cost (though not too much higher).
