Your question is a bit more ambiguous than you realize. Without taking into account what state(s) this vehicle is/are operating in, whether any permits are in effect, etc., the simple answer is that the combination would be limited to the same 80,0000 lb. gross vehicle weight as any other tractor-trailer is. 34,000 lbs. on the drive axles max, steer axle may have up to 20,000 lbs on it.
If you want to know what the weight limitations would be in accordance to the federal bridge law, see the related link at the bottom for a source where you can calculate it, but bear in mind that, if that is a 38 ft. trailer you're working with, you'll need to replace the given bridge measurement between the drive and trailer axles with the distance between the drive and trailer axles of your vehicle.

That really depends on what kind of trailer it's pulling. If it's pulling something like an RGN lowboy, or double drop trailer, that trailer may only have about two inches of ground clearance.
Yes, I can. Anything from a run-of-the-mill passenger car up to a 21 axle lowboy tractor-trailer combination.
Depends. But generally 25 to 35 tons Andrew Banks Global Transport
10,000 and up, depending on what type of trailer it is (e.g., dry van, refrigerated van, flatbed, stepdeck, RGN lowboy, beam trailer, etc) and what material it's made from.
RGN refers to the trailer - it means Removable Goose Neck. The neck of the trailer detaches from the body of the trailer, and equipment is driven onto and off of the trailer from the front. These are usually referred to as lowboy trailers, but could be beam trailers or pontoon trailers, as well.
You could drive it (or have someone else do it), you could rail load it, you could contract a tractor-trailer to transport it (depending on exactly what it is, this could require either a stepdeck trailer or an RGN lowboy).
