Surging/bouncing are not normal. Sounds like you may need to adjust the chains on your weight distribution hitch. With your trailer unhitched and level, measure the distance from the ground to the bottom edge of the side trim at both the back and front of the trailer--when the trailer is level the distance will be the same. Now, do the same with your tow vehicle. Then hook up your trailer with your weight distribution hitch chains set the way you are currently towing--the traioler and the tow vehicle should be level. If the back of the tow vehicle is lower than the front of the tow vehicle you need to shorten the chains on the weight distribution hitch and vice versa. Keep adjusting the chains until the trailer and tow vehicle are level when hooked up. Finallly, remember that when you add weight to the back storage area of your tow vehicle or to the trailer itselv the weight distribution chains may need to be moved again. Hope this helps.
