Roco made a nice flatbed trailer in their military line but it does not seem to be available currently.

The Promotex low boy Ed suggested above is nice for the money, and can be had for a good price on eBay. I got one about a year ago. The carry deck is 26 scale feet long. The gooseneck and rear axle set brings the total to 53'.
With heavy blocking you could perhaps extend the trolley over the rear of the trailer, depending on the length of the trolley.
It's a detachable neck trailer, and the model's comes off with a small single phillips screw undernieth. Dan
Generals Headquarters (GHQ) makes a magnificent low boy trailer model. It is hard to assemble, but it is gorgeous when complete.

You will probably need to do some kitbashing. Most low boys are intended for short heavy loads like construction equipment. A trolley car would be a londer load than most kits will handle from the box.
I saw a few of the restored trolleys brought into Tampa for the Ybor City TECO trolley line.
When they were on the low boys, the traction trucks were removed and hauled in on a seperate trailer. I do not have any pictures.
They had wide load banners and escort vehicles.

Kevin,
Alloy Forms makes cast Pewter kits if You prefer them to plastic RTR. A 37ft HD lowboy tandem axle trailer and a 45ft HD lowboy 14 tire tandem axle:

I added extras to the ones I built. Like bulkheads made out of brass sheet and Lonestar real wood decks.
I used Zap-A-Gap Medium CA +, for adhesive.
The 37ft. one:
The 45ft. one:
All the vehicles above, are cast Pewter kits. Woodland Scenics/Alloy Forms.
Take Care!

The Norscot looks like a possibility, too?

Back in 2018, I first visited the Pennsylvania Trolley Museum, and for a couple days afterwards, I got to thinking about switching to a trolley layout. While I decided to then stay with my current layout, I remembered an old Bachmann single-truck trolley that I had in storage from when I was a kid. I managed to find it, and while it doesn't run very well (not that it would look right running next to freight trains and Amtrak on the mainline), I got an idea looking through the book I got from the museum of how to incorporate that trolley into my layout. In the book, they had some pics of the trolleys being transported on flatbed trailers to the museum. So what I'd like to do is convert the trolley into a trailer load, perhaps heavily weathering it, to make it look like it's on its way to a museum for preservation/restoration. Anybody have any suggestions for flatbed/lowboy trailers that would be appropriate for this?
