New to travel trailers

Thanks for all the advice so far. We have been looking at smaller trailers too, but can't find any that would suit us yet. We are also considering a 2013 Forest River Rockwood Signature Ultra Lite 8311SS, this trailer would suit us better than anything else we've seen. It is about 1.5 feet shorter and 500-600 pounds lighter than the Outback. Our truck is rated for 8,600 lbs and the GVWR on this one is 8,450 lbs. The unloaded vehicle weight is 6,951 lbs. We probably would never fill the trailer anywhere near the GVWR. Would this be at all possible for us to tow even at a low speed? We will be driving slow no matter which one we get. We will always be in campgrounds that have pull through, paved sites and will only be taking the trailer on main highways and will be doing as little maneuvering and backing up as possible. Also is there anything that could be done to our truck that might make towing something like this a little easier or more stable?
