OK, here is a couple of options I've seen or helped load and unload.
The removable [ steel or alum] or non-removable rack for golf cart works by making the roof of the golf cart removable, then load the cart 1'st, then load your FED in so the front-end is under the cart.
Option two is back your FED into the trailer, and move the front end to one side of the trailer [ use a patch of carpet to protect my wire spoke wheels], and the load the cart next to the dragster on the other side. This would be a good option if you want to use your cart before and after you have loaded the race car. And you may be able to hang the JR over the FED, just make sure your trailer can handle the weight of the JR, or build a frame support inside the trailer.
The most inventive trailer loading I've seen was, in a 24' trailer [or maybe shorter], had a big removable tool box, a Chevy II [ Super Gas], golf cart, and a FED [ A/ND] with the front end hung from the roof. He had installed a steel frame inside the trailer to tie the dragster front-end to, so the front of the dragster hung over the Chevy II. OH Ya, the big stackable tool box in the front of the trailer.
YUP, all this in a two axle trailer. Sorry I have no pictures or not sure of the size of the trailer.
Of course the amount of floor space you are using for tool boxes, work benches, wheels/ tires, etc may have to be relocated.
So get out your measuring tape, and have fun !
