Something like this mounted to the a-frame should do the trick:
I have my doubts about that, the fastaway bars, at least on our hitch are rectangular and heavy. Maybe 8 or 10 pounds. Your welding shop idea is workable but I don't get the problem with dropping them in the bed of the truck. If his are coated with grease then he is doing something wrong. Fastaway recommend lube only at the contact points. The ends of the bar. Carry a rag or two and wipe it off.

I don't get why they are greasy and can't be tossed in the truck bed but since the OP was insistent he had no space, some sort of rack would work.
If they are too big or heavy, a welding shop adding some upright pipes in a similar configuration would work. It would also be a convenient storage place while the trailer is parked.
