Depends on make, model and options. Average empty weight is 15,000 lbs.
You can weigh your tractor and trailer at any Pilot, Loves, Circle K, any truck stop with a Cat Scale (Big Yellow Sign that says Cat Scale).
Durabilt is one of the best types of trailer that are availabel for your truck. Vulcan is another big name in truck trailers that is very popular
This answer is for the US: As big as you want, but if it hangs over the sides or ends of the trailer, or is higher than 13'6" when it's on the trailer, it has to be permitted and marked as an oversize load. If it makes the whole truck weigh more than 80,000 lbs, you need additional axles and a permit to haul overweight loads.
Big truck, semi, 18 wheeler.
As big as they are now. Bob Chandler created the monster truck with the first Big Foot.
I don't know how tall it is, but it is 53 feet long. It says this on the trailer.
21,000 lbs ??? wow that's big for an RV If we use the rule of thumb that pin weight should be 10% of the overall trailer weight the pin or hitch weight should be 2,100 lbs The kink in this is that loading of the trailer greatly affects this. The best way to calculate this is to find a scale to weigh trucks (there is a public weigh it yourself near my house) Then weigh the towing truck alone Then weigh the truck only while it is connected to the trailer. The additional weight is the hitch weight. This is accurate and will ensure you are within the safe limits of your combined unit.
it depends how big the foot is.
Truck Stop Missouri - 2011 Big Foot 1-14 was released on: USA: 12 April 2012
This depends on several factors. How big the truck and trailer are. How old is the truck. New trucks are more energy efficiant. Is the trailer loaded or empty. If loaded how many horses are being trailered. Newer trucks pulling trailers get about 17 to 22 miles per gallon.
24 foot minimum, but if you are like me and have lots of stuff, you;ll need the 30 foot truck to fit it all in.
35,000 - 40,000 lbs, all things dependent. There'll be a big difference between, say, a Western Star 4964EX pulling a 40 ft. steel rock tub and an aero truck pulling a 28 ft. aluminum framed dirt tub.
