Hello from Texas City!
That is a lot of trailer for a 3/4 ton. Without having duals you also loose some stability. A good question is, what is the king pin weight when fully loaded? Will the tires hold up to the load capacity. Is the truck a long bed or a short bed? Short beds can handle more pin weight (If I remember correctly).
Here is the biggest kicker of all. Will the brakes be able to handle the stopping? Yes, l the trailer has brakes, but the truck does most of the stopping.
Is the present truck equipped with the tow package? If not, I would not do it for sure.
Good luck, and happy trails.
