I flat towed my cj3a with my XJ, no problem.
Just depends on where and what you are doing.
Last weekend, I helped some mexicans who were pulling a trailer with 4 horses with a 318 dodge.. burned up the motor pulling the Jellico Pass in Tennessee. Probably was fine for them for some stuff, but the heavy use killed it.
Again, just depends on what you are doing. That setup down a mountain grade would be scary.
