You will be fine. I had my Tige and towed it with a Nissan Frontier (3.3L). I towed that thing quite a ways, up hills. I had a stick too. ... One ramp we have is pretty steep. I would put it in 4L, otherwise, I couldn't get it going. It would stall.
Since you aren't going far, you will be fine. The real problem, is the smaller trucks don't have the weight to stop the trailer on the highway. If something happens.
Just go slow.
