45,000

Answer 2

There's a lot of factors here. First and foremost will be the legal weight rating of the trailer. This information should be found in the trailer's registration. There's also the trailer type, which you did not specify. If you're pulling a trailer attached by a ball hitch, then you also have to factor in the tongue weight, and what the permissible tongue weight of the tow vehicle is. Often, you'll see cars and light duty trucks and vans pulling trailers with excessive tongue weight. As a result, the rear end of those vehicles is very visibly lower than the front end. This makes for a very unstable and dangerous vehicle going down the road.

When it comes to commercial semi trailers, there's a whole new set of laws pertaining to this. The federal gross weight limit for a five axle unit is 80,000 lbs without requiring permits. Some states allow higher weight limits for intrastate only use.
