The semi-truck without the trailer weighs around 20,000 lbs. An empty trailer weighs around 12,000 lbs, but it depends on what type of trailer it is. There are hundreds of different configurations. The point is...the maximum legal weight that an 18-wheeler can weigh is 40 tons (80,000 lbs).
The total weight doesn't really bother me much, its still 1,200 lbs less than what my manual states as the max trailer weight, and I doubt I will ever be able to fill the trailer up to its max payload. The one thing I'm worried about is the pin weight on my rear axle. The axle is rated for 6048 lbs. 20% of the 5th wheel weight is 2,800 lbs, which is what I'm told to use when calculating this weight. I've read on several websites that the rear axle weighs about 3,500 lbs when empty.
