It could work if you load it properly and are aware of where you are. I tow small myself. I am aware that full of water (which I only do when I go weigh) and fully loaded, I am under all axle ratings and 100lbs over GVW and under GCVWR. I never tow above 60 and I have a quality WDH.
Now, you won't have the most pleasant experience. You will want to take it slow. I would look and see if something smaller may suit you.
Also, do NOT let dealers talk you into things. I was at a show this weekend and I could tow the world! I got things like (If you lightly pack, you could tow this until you upgrade. NO WAY!
So far, you are taking the right steps and getting educated. Just remember, there are 3 groups of people.
1) If it pulls it, you're good.
2) Know your limits, and there is room for fudge factor.
3) All ratings are law, and you need a one ton to tow everything.
Most of all, be safe. You can't enjoy life when you are decomposing in the ground.
